"Interestingly, you can buy fireworks at Walmart stores in Arizona. You aren't supposed to light them all at once inside the store, though. The gentleman who did will soon learn that fireworks are harder to come by in prison."
Won't say, 'well, can you blame them?' but interestingly enough, in Phoenix, it is legal to buy fireworks, it is legal to sell fireworks and it is legal to possess fireworks. It is, however, illegal to use them. Go figger. (I just moved from Phoenix to the East Coast about a month ago)
