Well, I guess it's time to take all the guns away from law enforcement agents...
Every agency my brother has ever worked for (3 different ones) required extensive psychological testing. We've all got a breaking point but shooting a colleague/boss in the office, even if he is a jerk? I wonder if there were any subtle signs from the shooter before he lost it? I suspect that there will be some ridiculous knee-jerk reaction to this from the ICE administration. Maybe a "check-your-guns-at-the-door" policy?
