JFC you guys are almost as bad as the righties with the “no one on the left could’ve done this” rhetoric.
Newsflash: There are plenty of people on the left with guns, well trained with those guns, and highly capable, if sufficiently motivated, of committing an act like this. Just because they don’t loudly shout to the world about their ability to shoot someone, doesn’t mean they won’t actually do it.
And you don’t think there aren’t leftists itching for a civil war as well? Again, just because they’re not shouting it out to the world doesn’t mean they don’t exist.
