I have no idea if, or for what, he is sorry for. If he did commit a crime, he should be punished. My response to you was in regards to your characterization that all cops are liars. Now you know that is not true, and if you still state so, you are being disingenuous.
If?
I still maintain that it's safer to assume that all cops are goons and be pleasantly surprised than to assume that all cops are nice guys and find out the hard way that I'm wrong.
I'm sure cops do the same thing with everyone they meet, too.
