I guess I didn't make my self clear, if the guards were involved in any way, either by direct action, or indirect action (indiference)then they were wrong, and as you state a jury awarded monies to MR. Roberson because of the actions/inaction of guards
But what you said is...Had the guards somehow recognized that a witchhunt was in progress they might not have allowed Roberson to be beaten up.
I could say, had the Wright bros. somehow recognized that airplanes would be used as weapons they might not have gone to Kitty Hawk.
But it's a bit discomfiting to hear those who one expects to lead with their heads (the conservative says: "I think that...") instead of their emotions (the liberal says: "I feel that...") do exactly the opposite.
I hope that wasn't directed at me, I think, no, I feel like I might cry, oh damn that Rush Limbaugh!
There, there. :-) LOL. No, it wasn't.
