Cops blow whistles, when they dirrect traffic; is this the same concept as a government Whistleblower?

Question

Do the governmental officials so hate cops that they call someone who tries to stop corruption a cop ~ but in a mocking dirrisive way???

Answer 1

No, actually it would be more akin to a teacher monitoring a playground.

Answer 2

No. Think more about a referee blowing the whistle for a foul.  

Answer 3

No.  It's more like a very lame and unsuccessful attempt at humour.  Some people (no names mentioned) do very poorly at that..
