soundofreason...He apparently got released from HPD because of his habit of pulling his firearm when not necessary. Apparently his training did not help him as far as his discipline with fire arms. His "HGEA quality knowledge" was one he didn't learn that's why he was fired from HPD. With training, like schooling, you can lead them the right way but you can't be sure it sinks in. 
In this situation, the "union" wasn't there to make sure he made a good decision. At the same time, one man doesn't make an organization. He might be just one who made a bad decision or good as the investigation will uncover.
