Dude,

interesting story about your aunt, and it's consistent with some of the public comments by law enforcement the past 4 years following violent clashes between police and citizens.She knows you and may have helped raise you, yet you are a "cop hater" for asking questions.
Depending on what kind of a cop a person is, it's a dangerous job and I understand why they may adopt the "pack" mentality.However police can judge/jury/executioner in encounters with people and that's not a responsibility to be taken lightly. Fairness and humanity have to override any "us against them" mentality or you stop being police and you become like an occupying army or something.
