He was riding his bike with a Monster and no helmet.
That's just idiotic.
the cop searches him, and finds a huge ass pocket knife. The cop at this point believes my friend is in a gang (although he's white)
Way to be tribal. Die in a fire.
the cop takes him down to Rite-Aid and soon discovers my friend shop-lifted the Monster.
Well then your friend is still an idiot.
my friend breaks out of the cuffs and ditches.
Your friend is just a total idiot. He should be fined or something.
I don't see the problem here. Your friend is a fiend. He'll probably be a drug addict in two years and he'll be a Highschool dropout soon if he isn't already.
