From what I understand, AUS police are run entirely at the state level? Your "everyday" police in the US are typically controlled by a local city or county, the value of which is now more apparent than ever, as it avoids the state and federal government from politicizing the police force as what's happened in AUS. We have "State" police, but their presence is typically limited to highway patrol and big events.I'd wager it's 'progressive' & PC hiring practices.
Rather certain they don't want the best & brightest to enter the police forces here.
They want the pliable puppets / thugs.
