The area that my grandparents live in is getting very violent as of late; kids killed a hobo with a brick for his bike, neighbors houses get robbed, a skinhead recently got out of prison and did a drug deal right in front of their house, and last night a truck ran into a nearby convenience store and robbed it. I want to get them something to defend themselves in case someone tries to rob them (She's 60, he's 50 her other two husbands both died), however there may be complications.
My grandfather is a convicted felon; when he was younger he would sell illegal weapons and drugs across the country, once he got out though he hasn't done it since. The problem here is that I'm afraid if he uses a weapon in SD that he himself might also get arrested or that I also might get arrested for knowingly allowing a firearm to be where a convicted felon can acquire it. What do?
