Sorry if this has already been posted.. I searched and couldn't find it.

It just makes my blood boil...

In an Urban Institute study for the Department of Justice (pdf), Jeffrey Roth and Christopher Koper find that the 1994 Assault Weapons Ban was responsible for a 6.7 percent decrease in total gun murders, holding all other factors equal. They write: “Assault weapons are disproportionately involved in murders with multiple victims, multiple wounds per victim, and police officers as victims.”

Guess what.... all other factors are NOT equal!
