Here's how you become one of those people who screams at his kid's coach.
First, Houston's DNA lab became a laughingstock. Then its controversial director was murdered.
Detective Woodings of the LAPD seems to agree with that rather bleak assessment. "We caused the escalation of violence ourselves by putting more preventative measures in place. The crooks just take countermeasures," he says.
"We might as well stand on the corner and give the jewels away. Then there would be no more robberies."
