If I saw him following some little old lady, I woulda stopped and waited for him to do the same, then put him into the wall while someone called the police for me. I'm sorry, but the of some dirt bag doing that to my grandma makes me livid. Besides, if he spends the night in jail or what not, atleast he has a roof over his head and a meal. Maybe he'll flip out when the cops come and they can legal 2000 him and maybe get him some help.
