The LEO(s) quoted in this post by rsa-otc:
"Most LEOs I talk to now a days have told me that if someone points what looks like it may be a gun at them and that person fails to obey commands they will respond with lethal force. Orange rings on the muzzle. Or looking like it could be a toy be dammed."
Let the average none LEO try defending "He pointed a bright orange toy looking gun at me and I told him to put it down but he didn't so I killed him".
