Why do parents always seem to blame the police?

When their kids are caught doing something wrong instead of blaming their own lack of parenting skills. There was a 13 year-old in Seattle that was shot in the leg by a police officer because he was not listening and instead of showing his hands like asked he was reaching for something in his pocket. It happened to be a cell phone, but how was the cop supposed to know that. Why is a 13 and 14 year-old out at 3am anyway. Where were their parents? His dad of course said "He was complying with the cop". What a crock! If he was complying he would not have been shot! Parents need to be parents and teach them right from wrong and not let them run wild at all hours of the night. It is not the police department's job to keep track of your kids!
