So long story short a buddy I went to high school with ended up on drugs and is now hanging around my neighborhood. I live in a shitty part of Louisville. He's shown up twice now. Once for a chat the second time to beg. Any suggestions on security cameras and the short? Already got the gates padlock ed. I know of the type of people he is running around with too, the tweakest of tweakers, so I bought a mossberg maverick 88. Just any suggestions I can do on the passive side of home defense?
