This gets uglier:

Not to derail this thread, but this is one reason that I have some tribulation about what we call "lateral transfer" hires. There is an issue of "problem child" cops being shipped around from dept to dept with conditions of their leaving the last job being sealed as part of a "deal".
I almost always prefer to hire "fresh cops" vs. taking an officer from another dept sight unseen. "Fresh Cops" have to make it through the academy, they have to go through feild training and in most agencies they are placed on a probationary period where they can be fired almost immediately if they do not work out.
There is now a trend in LEO hiring where "lateral transfer" hires are asked to sign a release so that the new agency can get their "entire story". This cop looks like a poster boy for this new approach.
