The problem with cracking down hard is that as soon as they start, the Whiteaker residents as well as south Eugreenies will start screaming racism and police brutality.  Then the cries against profiling will start, bringing the BLM folks rolling into town.  The police chief will be fired or resign, police officers will be charged as criminals and the gangs will once again be allowed to do their bidding.  You can 't crack down hard without have collateral crack down occurring.
