Feel-good policy. Dealers kill each other all the time, yet new ones keep springing up; thanks to the drug war's hyperinflation of drug prices, the money is just too good for many to turn down. And the odds of a competitor catching a dealer are much higher than the odds of law enforcement catching him.
I advocate dosing each dealer with whatever he is selling at he time of his capture.
That'll teach those pot dealers.
Pot and the accompanying stupidity will be legal by then.
