This is just the "not all cops" with more words. Where are the good cops?
They aren't turning people in. They aren't speaking out. If they do such things, they get fired. They aren't getting promoted: Speaking out makes you untrustworthy.
They aren't doing this so much that we know there are police gangs. With tattoos and everything. Surely, folks knew, but nothing happened. Simply not acting like the bad cops isn't enough to be a good cop.
The only real reason we have evidence of police misconduct is because of modern technology: The only reason Rodney King's abuse got nationwide coverage is because it happened to be on video, and now everyone has a camera in their pockets.
And little has changed.
Where, exactly, are these good cops and what are they doing?
