I think it was a single shot to the chest. It doesn’t look like an “assault weapon” with a 30 round clip was used.
Old-time US criminals NEVER carried out revenge attacks on law enforcement: it drew too much heat. But now, between international terrorism and the Mexicifation of America, this may change: Mexican gangs have been fierce in retaliating against/intimidating Mexican officials and police. Why would they not try it here? Quick , let’s legalize 11 million illegals. We had a great country once: it is being destroyed from within by selfish, unpatriotic politicians. The Democrats are the worst—there is not a real American among them now—, but many Republicans no better. God help us.
