It’s the way she goes.
Cops are humans. They’re vulnerable to the same emotions, stresses and faulty reactions as everyone else.
Training can only achieve so much.
If you’re a law-abiding and decent person, interaction with law enforcement, over a lifetime, will be extremely limited. Speeding ticket maybe, etc.
However, if you’re a no-good dufus, doing drugs, committing crimes and being of a generally poor behaviour, you’ll seemingly always be dealing with officers.
Now add a shit attitude towards those officers and a resistance to compliance and there’s a very real possibility you could eat dirt and get fucked.
Like any arena of life, crap people also exist in cop land, but a majority of police officers are regular folks not looking for trouble.
