I realize Charlie Kirk was not President (yet), but how about a little security at outdoor political events? Why not station a trusted officer on top of the highest roof to keep an eye out for someone who should not be up there? One policeman on the highest roof could monitor all the high places.
Tell you what... From what I see there were three roof top security posts. And one ran away after taking the shot...
about a little security at outdoor political events? >>. I think they should all use canopies that will sheild them from upper areas. and move around a lot. Not sure i would trust a watcher.
