Violence flares in Egypt after emergency law imposed
CAIRO (Reuters) - A man was shot dead on Monday in a fifth day of violence that has killed 50 Egyptians and prompted the Islamist president to declare a state of emergency in an attempt to end a wave of unrest sweeping the biggest Arab nation.
Emergency rule announced by President Mohamed Mursi on Sunday covers the cities of Port Said, Ismailia and Suez. The army has already been deployed in two of those cities and ministers agreed a measure to let soldiers arrest civilians.
A cabinet source told Reuters any trials would be in civilian courts, but the step is likely to anger protesters who accuse Mursi of using high-handed tactics of the kind they fought against to oust his military predecessor Hosni Mubarak.
Egypt's politics have become deeply polarized since those heady days two years ago, when protesters were making the running in the Arab Spring revolutions that sent shockwaves through the region and Islamists and liberals lined up together.
Although Islamists have won parliamentary and presidential elections, the disparate opposition has since united against Mursi. Late last year he moved to expand his powers and pushed a constitution with a perceived Islamist bias through a referendum. The moves were punctuated by street violence.
Mursi's national dialogue meeting on Monday to help end the crisis was spurned by his main opponents.
They say Mursi hijacked the revolution, listens only to his Islamist allies and broke a promise to be a president for all Egyptians. Islamists say their rivals want to overthrow by undemocratic means Egypt's first freely elected leader.
Thousands of anti-Mursi protesters were out on the streets again in Cairo and elsewhere on Monday, the second anniversary of one of the bloodiest days in the revolution which erupted on January 25, 2011 and ended Mubarak's iron rule 18 days later.
"The people want to bring down the regime," they chanted Alexandria. "Leave means go, and don't say no!" they shouted.
VOLLEYS OF TEARGAS
Propelled to the presidency in a June election by the Muslim Brotherhood, Mursi has lurched through a series of political crises and violent demonstrations, complicating his task of shoring up the economy and of preparing for a parliamentary election to cement the new democracy in a few months.
Instability in Egypt has raised concerns in Western capitals, where officials worry about the direction of a key regional player that has a peace deal with Israel.
In Cairo on Monday, police fired volleys of teargas at stone-throwing protesters near Tahrir Square, cauldron of the anti-Mubarak uprising. A car was torched on a nearby bridge.
A 46-year-old bystander was killed by a gunshot early on Monday, a security source said. It was not clear who fired.
"We want to bring down the regime and end the state that is run by the Muslim Brotherhood," said Ibrahim Eissa, a 26-year-old cook, protecting his face from teargas wafting towards him.
The political unrest has been exacerbated by street violence linked to death penalties imposed on soccer supporters convicted of involvement in stadium rioting in Port Said a year ago.
As part of emergency measures, a daily curfew will be imposed on the three canal cities from 9 p.m. (1900 GMT) to 6 a.m. (0400 GMT). Residents have said they will defy it.
The president announced the measures on television on Sunday: "The protection of the nation is the responsibility of everyone. We will confront any threat to its security with force and firmness within the remit of the law," Mursi said, angering many of his opponents when he wagged his finger at the camera.
He offered condolences to families of victims. But his invitation to Islamist allies and their opponents to hold a national dialogue was spurned by the main opposition National Salvation Front coalition. Those who accepted were mostly Mursi's supporters or sympathizers.
SENDING A MESSAGE
The Front rejected the offer as "cosmetic and not substantive" and set conditions for any future meeting that have not been met in the past, such as forming a government of national unity. They also demanded that Mursi declare himself responsible for the bloodshed.
"We will send a message to the Egyptian people and the president of the republic about what we think are the essentials for dialogue. If he agrees to them, we are ready for dialogue," opposition politician Mohamed ElBaradei told a news conference.
The opposition Front has distanced itself from the latest flare-ups but said Mursi should have acted far sooner to impose security measures that would have ended the violence.
"Of course we feel the president is missing the real problem on the ground, which is his own policies," Front spokesman Khaled Dawoud said after Mursi made his declaration.
Other activists said Mursi's measures to try to impose control on the turbulent streets could backfire.
"Martial law, state of emergency and army arrests of civilians are not a solution to the crisis," said Ahmed Maher of the April 6 movement that helped galvanize the 2011 uprising. "All this will do is further provoke the youth. The solution has to be a political one that addresses the roots of the problem."
Rights activists said Mursi's declaration was a backward step for Egypt, which was under emergency law for Mubarak's entire 30-year rule. His police used the sweeping arrest provisions to muzzle dissent and round up opponents, including members of the Brotherhood and even Mursi himself.
Heba Morayef of Human Rights Watch in Cairo said the police, still hated by many Egyptians for their heavy-handed tactics under Mubarak, would once again have the right to arrest people "purely because they look suspicious", undermining efforts to create a more efficient and respected police force.
"It is a classic knee-jerk reaction to think the emergency law will help bring security," she said. "It gives so much discretion to the Ministry of Interior that it ends up causing more abuse, which in turn causes more anger."

Soldier who lost 4 limbs has double-arm transplant
The first soldier to survive after losing all four limbs in the Iraq war has received a double-arm transplant.
Brendan Marrocco had the operation on Dec. 18 at Johns Hopkins Hospital in Baltimore, his father said Monday. The 26-year-old Marrocco, who is from New York City, was injured by a roadside bomb in 2009.
He also received bone marrow from the same dead donor who supplied his new arms. That novel approach is aimed at helping his body accept the new limbs with minimal medication to prevent rejection.
The military is sponsoring operations like these to help wounded troops. About 300 have lost arms or hands in the wars.
"He was the first quad amputee to survive" from the wars in Iraq and Afghanistan, and there have been four others since then, said Brendan Marrocco's father, Alex Marrocco. "He was really excited to get new arms."
The Marroccos want to thank the donor's family for "making a selfless decision ... making a difference in Brendan's life," the father said.
Surgeons plan to discuss the transplant at a news conference with the patient on Tuesday.
The 13-hour operation was led by Dr. W.P. Andrew Lee, plastic surgery chief at Johns Hopkins, and is the seventh double-hand or double-arm transplant done in the United States. Lee led three of those earlier operations when he previously worked at the University of Pittsburgh, including the only above-elbow transplant that had been done at the time, in 2010.
Marrocco's "was the most complicated one" so far, Lee said in an interview Monday. It will take more than a year to know how fully Marrocco will be able to use the new arms, Lee said.
"The maximum speed is an inch a month for nerve regeneration," he explained. "We're easily looking at a couple years" until the full extent of recovery is known.
While at Pittsburgh, Lee pioneered the novel immune suppression approach used for Marrocco. The surgeon led hand transplant operations on five patients, giving them marrow from their donors in addition to the new limbs. All five recipients have done well and four have been able to take just one anti-rejection drug instead of combination treatments most transplant patients receive.
Minimizing anti-rejection drugs is important because they have side effects and raise the risk of cancer over the long term. Those risks have limited the willingness of surgeons and patients to do more hand, arm and even face transplants. Unlike a life-saving heart or liver transplant, limb transplants are aimed at improving quality of life, not extending it.
Quality of life is a key concern for people missing arms and hands ? prosthetics for those limbs are not as advanced as those for feet and legs.
Lee has received funding for his work from AFIRM, the Armed Forces Institute of Regenerative Medicine, a cooperative research network of top hospitals and universities around the country that the government formed about five years ago. With government money, he and several other plastic surgeons around the country are preparing to do more face transplants, possibly using the new minimal immune suppression approach.
Marrocco expects to spend three to four months at Hopkins, then return to a military hospital to continue physical therapy, his father said. Before the operation, he had been living with his older brother in a handicapped-accessible home on New York's Staten Island built with the help of several charities.
The home was heavily damaged by Superstorm Sandy last fall.
Despite being in a lot of pain for some time after the operation, Marrocco showed a sense of humor, his father said. He had a hoarse voice from a tube in his throat during the long surgery, decided that he sounded like Al Pacino, and started doing movie lines.
"He was making the nurses laugh," Alex Marrocco said.

Precious Metals & Miners Making Waves and New Trends -- MrSwing
The precious metals sector has been dormant since both gold and silver topped in 2011. But the long term bull market remains intact. As long as we do not have the price of gold close below the lower yellow box on the monthly chart then technical speaking precious metals should continue much higher.
Large consolidation periods (yellow boxes) provide investors with great insight for investments looking forward 6-18 months upon a breakout in either direction (up or down). The issue with investing during these times is the passage of time. One can hold a position for months and sometimes years having their investments fluctuate adding extra stress to their life when they really do not need to.
Once a breakout takes place a powerful rally or decline will start putting an investors? money to work within days of committing to that particular investment compared to money invested waiting months for the breakout and new capital gains to occur.
Gold Price Chart ? Monthly
?
Gold Price Chart ? Daily
The chart of gold continues to form a large bull flag pattern with a potential 3 or 5 wave correction. If price reverses this week and breaks above the upper resistance trend line then it will be a 3 (ABC)? wave correction which is very bullish. But there is potential for a full 5 wave correction which is still bullish, but it just means we have another month or two before metals bottom.
?
Gold Miner Stocks ? GDX ETF Chart ? Daily
Gold miners do not have the sexiest looking chart. It was formed a strong looking bull flag but has continues to correct and is not nearing a key support level. This level could act as a triple bottom (bullish) or if price breaks below then it would be breaking then neckline of a massive head and shoulders pattern which points to 50% decline. I remain bullish with the longer term gold trend until proven wrong.
?
Silver Price Chart ? Daily
Silver remains in a long term bull market much like the monthly chart of gold shown earlier in this report. Silver continues to work its way through a large bull flag pattern with a positive outlook at this time.
?
Silver Miner Stocks ? SIL ETF ? Daily Chart
Reviewing the precious metals sector it seems that silver miners have the sexiest looking chart. All price patterns are showing strength and are in proportion to one other. If this chart plays out to what technical analysis is pointing to then we could see the precious metals sector put in a bottom and rally within the next week or two. And if this is the case then silver miner stocks should provide the most opportunity going forward.
?
Precious Metals Trading Conclusion:
In short, what you need to focus on is the yellow consolidation box on the monthly gold chart. A breaking in either direction will trigger a massive move that should last 6-18 months. Until then long term investors can simply sit back and watch the sector while they put their money to work in other active sectors.
From a short term traders point of view, that f mine. I am looking for a signs of a bottom on the daily chart to get my money working earlier to play the bounce/rally that takes place and actively managing the position until a breakout occurs. The charts overall are not that clear as to when a breakout will take place. Metals could start to rally next week or in a few months and all we can do is wait for a reversal to the upside before we get active.
Knowing the big picture trends and patterns at play along with major support and resistance levels (breakout levels) is crucial for success and piece of mind.
