Absolutely.
If someone was firing from a window 300 yards away at me or mine, I’d be loading that room full of 7.62’s like they were on sale.
Moreover, he was firing to 1300 feet, but the distance from intersections to mobilize at was in the 150-200 yard range. Even I can hit a guy leaning out of a window at 150 yards.
leaning out of what window??? you don't even see muzzle flash in the videosHmmm. If I were in the crowd with my family and somehow armed with a good rifle, I might, but probably not from 1300 feet, 30 stories up.
If I were in a closer position with my family and a hunting rifle, and he wasn't shooting at us, I'd probably seek cover.
If I were a cop in a position close enough to shoot at him (no threat to my family), I don't know. I have no idea what their training is in such situations.
BTW, did you read somewhere he was leaning out the window? I hadn't heard that.
