I bet the cartridges were wiped clean and handled with gloves during loading so the prints won't burn onto the surfaces when fired.
Probably sterilized the rifle too. This was obviously a hit, but the shooter was skylining himself on the roof.
Not a professional, but dedicated in the planning. Was probably very familiar with the campus, maybe a student. Or cased the area for a few weeks beforehand. He had help in my opinion. The Boys are looking at all cameras for cars/him probably in a 1 mile radius.
He might have gotten away for now, but the tranny gun groups are 100% guaranteed are gonna get some FBI/ATF loving.
