I would imagine I was fairly typical . I would suspect that even more 20 yr olds smoke pot now than did then. But that could just be bias on my my part.
Guns are a very common thing in our country , mostly rifles and such, but I can think off the top of my head of at least 20 immediate friends who own handguns , plus family.
If you want to get a gun, it's not difficult. (he got his hands on 3 from his mom, didn't even have to go the illegal route).
banning gun in the USA will not happen for the next 500 years or so. if ever. it's too much a part of our culture, it would be like banning cheese in France
