My neighbor wont stop farting?!?

Ok seriously my damn bronco football obsessed neighbor is farting in my bushes? I just moved into this apartment, im upstairs petting my cat at the window and i happen to see him and im wondering why hes suspisous and he just farts really loud. Its not like random.. He walks his dog and passes by but he does it a lot its really weird. Calling the cops wont do anything, the owners of the apartments or duplex dont have time for this. I mean i dont even know the guy and its like he has something against me? He doesnt look like a drug user, he only drinks beer and smokes cigrarettes.. What do i do?..
