Cop or not. Slitting the throat of a dog?

And, apparently, at this time, No longer a cop.

Which is good, sorta. Thing is, how did a person like this ever become a cop. How did his fellow cops not see the psychopath inside him? And if they did, then how was he still a cop?

I know, the Blue Line/Blue Wall….Which is why the police aren’t respected anymore.

I’m not trying to bash cops here…thousands of cops did everything right yesterday, harmed no one, and treated everyone they met well.

But how is it that a cop could do this?
