I too have worked with cops on emergency scenes for about eleven years. Mostly, they are good people. The operative word is people. And the important word is good. They got into the business of law enforcement because they want to effect positive change. In my world, they are the folks I help pay to protect my kids, my neighbours and me. They carry 9 mm pistols so that I don't have to. They go to work wearing bullet 'proof' vests on my behalf--bullet proof until some sick bastard produces teflon projectiles. The situation was tragic, and I do not for a minute doubt the officers (marshals) involved will undergo CISD--not because it's policy, but because they need it.
