I find it hard to believe that 'no one else had a weapon' if Scalise had a govt security detail present.
I just hate this. The GOP & alt right are going to have a field day if it turns out the shooter was a Dem or left-leaning. They're also going to use it to push for less gun control. One of our Trumpette friends already thinks that it should be mandatory that ALL adults have a weapon (a la Switzerland) in their home. After this, he's going to think we should all be toting them on our hips, John Wayne style.
It may not be a Dem, though. Plenty of the alt right are angry at GOP members of Congress for not rubber-stamping the Wall, ACA repeal, and other Trump idiocy.
