Well, I guess we've beat this dead horse enough.
Not one police officer has come forward with suggestions on how to improve their image or try to convince us that we have nothing to fear from them. The only responses so far have been to bash us for not kissing their collective asses.
Why should they care about image? It is not their job to convince us of anything.
I don't care what anyone's image is of HVAC contractors and I'm sure you don't care what people think about IT guys.
If you want to change the operational aspect of law enforcement, that begins with the Legislative Branch of government.
