We keep telling you that "warning" shots are a lousy idea :: 05/26/2014

  "A sheriff's deputy who allegedly fired his service revolver into the air after neighborhood kids pulled a prank has been arrested on suspicion of discharging a firearm with gross negligence, according to the Los Angeles County District Attorney's Office."
  If it's a bad idea for a Law Enforcement Officer to leave his home, become the aggressor, and fire a warning shot, why would it be a smart thing for you to do?
