install a motion detector for your front porch... soon as it beeps in your house, open the door, drag the little fucker inside and close the door. his mates outside will shit themselves and run off. the pisser will probably keep pissing and maybe shit himself but a quiet word in his ear about what will happen to him if it happends again. and take his wallet for his address and tell him youl come round and do various nasty things to his family. sorted!1
