The guy was acting erratic. Just because he lives there doesn't mean he might not be on drugs freaking out thinking he's about to get busted & pull out a gun. You know what would have been a better option? "Officer am I free to leave" if yes go inside & clean up another day. If no then slowly put down whatever you're holding, back/move away from it (is there a weapon in the bucket?) sit down & do what they say-you are being detained. Yes it is F-ed up but that is the world we live in.
