I know teaching can be stressful since it involves a lot of politics. I am very sure that police officers get tired of the same behavior from suspects they arrest.As a teacher, I get fed up with the same bad behaviors. Because they are repeated over and over, I tend to have automatic responses. I wonder if Officers tend to run into the same thing.
Cops are but human. They might be fed up by certain behaviors and I'm sure when you hear stories about a "suspect" being beaten up a cop, then maybe it's because they've done the same thing so often that the cops feel justified to vent out their frustration. Sure it's wrong but maybe if I was a cop the temptation might be hard to fight.
