This article is an awesome one that decribes how law enforcement management gets at Police Officers, most of whom are union members. From personal experience my opinion is that The City Of Northlake, Illinois’ Police Chief Dennis Koletsos uses this technique extensively.
After never having any complaints against me in 10 years on the job it was funny how after becoming our Union President I was suddenly being suspended and investigated for “anonyomous” complaints, etc…..
Those who have worked there know what I am talking about. Those except for the relatively few suck ups that would sell their soul if it meant getting something for themselves.
