Crappy dope. Crappy dope should be illegal. The narcs should roll around in the white narc car with their 229s under their sweatshirts and windbreakers, and jump out of their car and throw the dealers against the wall.
"Alright, give up the dope".
When the dealer hands it over, the narcs should cuff them and bring out a little tester vial, and drop a bit of the dope into the vial.
"Watch the birdie, scumbag", the narc should growl. "You know the drill. If the liquid turns green, you get let go. Yellow or orange, you're selling shitty fucking dope and we're taking you in."
The dealer's eyes are glued to the vial as the liquid starts to turn yellow... and then slowly fades into a deep green.
A smile spreads over the narc's face.
"It's your lucky day".
He uncuffs the dealer and hands him back his dope... but not before breaking off a good size chunk.
"To pay for the cost of the vial", the narc says, and winks before getting back into the narc car and driving off down the street.
