This is silly and short-sighted. There are many people who genuinely want to 'serve and protect', multiple generations in some families. Some people take duty very seriously and in good faith. Applying to be a cop in no way implies that a person holds arrests and the use of deadly force as anything other than a necessary component of the real-world, end-to-end justice system.

Honestly, I doubt this is true for most values of "many".
I'm a straight white male in a first world country with no criminal record. I have a good job and am a well-behaved citizen. I've lived all over this country and my experiences with the police have been uniformly negative.
Thugs interested in proving to everyone that they're in charge, that's all they are.
