We just had an another cop shooting, this one in Baton Rouge, where police recently shot Alton Sterling and then went postal on protestors:

Three police officers were killed after a gunfight in Baton Rouge, Louisiana on Sunday and three injured, one critically. The gunman was also killed, and police said they do not believe any other suspects currently threaten the city.

President Obama condemned the shooting and said attacks on police were “attacks against all of us and the rule of law that makes society possible”.
At about 8.40am officers responded to a report of a man with a rifle and wearing black by a convenience store, state police colonel Mike Edmonson told reporters late on Sunday. Two minutes later, shots were reported over police radio, a recording of which was posted online.

You just have to love American gun culture and American Law enforcement culture.

Enough is f%$#ing enough.
