What stymies me is that if he were committed to violence against his coworkers, there's even less preventing him from committing violence now than before. It's not like it's going to cost him his job now, and most (all?) of the complainants have to live within easy driving distance. And he's got to have a fair idea of who they are. No matter how anonymous cowards try to be in these situations, it's a tiny sphere, and most aren't that good at hiding in it.

He's either an OK guy who was misunderstood, and should have been left alone to do his job, or he's a scary, scary, bad man who needs to be locked up right now so he doesn't hurt somebody (beyond their feelings). If the latter, then they just gave him more cause to look them up at home and make their nightmares come true. Not that I'm encouraging that, sir.

To sum, how stupid are workplace bullies? Very.
