The people were misled. "Then we noticed, after they started firing, the insignia of the Presidential Guard," Dr Mina said. She said the injured claimed to her that they saw the Guard, an elite corps of 90,000 men answerable directly to President Hosni Mubarak, bringing ammunition to reinforce the defences of buildings such as the Interior Ministry and General Assembly.
"This wasn't firing into the air, or into people's legs," she said. "This was not trying to frighten people. When you shoot into the head and chest you are killing people."
She and others went out to try to persuade the lines of soldiers to allow ambulances through. She was told to come forward alone, as a doctor, and informed that ambulances could come, but could not be guaranteed safe passage. This was not his decision, the officer made clear.
http://cpj.org/2011/02/mubarak-intensifies-press-attacks-with-assaults-de.phpExplains way too much and yes, regular army troops is one thing. Presidential guard, ANYWHERE in the world is another... the Army may be showing splits, internal splits.
Oh and not allowing ambulances and not guaranteeing their safe passage is a violation of the geneva convention.
