Do you honestly think a kid like that would honestly have enough balls to go get marijuana? At least the extra effort and time might just give the guys some time to actually consider what they are doing, or even leak and hint towards it blantantly.
A kid like... what? If they're looking to get a gun, obviously they have some sort of 'balls', as you put it. Parents have guns. Kids can get guns from their parents. It's happened before. In some cases, parents have marijuana. Kids get marijuana from their parents. (Don't doubt me on this-- my dad's ex-wife ((who is not my mother, btw)) kept marijuana in their bathroom drawer to help with her depression. Or at least, that's what I think it was for o_O; I was always too nervous to ask. Anyway, my old step brother got into it a few times. He had a bedroom in the basement, so evidence was kept well hidden. I went down there to clean once and found bongs made with pop bottles and straws >__> But back on topic!) And what delinquent who goes out looking for drugs/guns actually considers what they're doing? That's why they get caught; that's why they get in trouble.
