What would you do?

Yeah he is a blood relative and hes 40 years old. Magnum dart, i feel ya, my grandmother if asked if shes scared of him says no. Yet she has locks, chains and anything you can think of to try and stop a meth head from entering your house on each of her doors. When talking about him, she sticks up for him, except for when he goes nuts breaks windows, doors, knocks the frames from doors out of walls, steals her car(s) and gets them shot up or sells for his fix.. Its sad because its family, but its his life ya know..
