The photo showed two black men pointing guns at a white police officer.  Mayor Nutter says the Brown and Garner deaths, each at the hands of white police officers, have created a volatile situation in our nation.

“This is a particular time of anguish across the country that citizens are feeling, that law enforcement are feeling,” Nutter said today, “so I think, we just at a certain point need to calm ourselves down, be mindful of the impact that our actions or comments or statements can have.”

The mayor says the paramedic has made an online apology but, he adds, we live in a technology-driven world in which it’s hard to take down or remove that kind of information.

Nutter also says the fire commissioner is conducting his own investigation into the matter.
