Like arresting the drug users and letting the dealers and suppliers and smugglers go free.
If you kill the suppliers, new suppliers will take their place.

The price of death is the price that will be paid on the street.

You can keep killing more and more, but, in the end, you'll just make it more profitable for the amount that does get through.

Look at Bush's cocaine habit. With those millions, he can afford whatever the street price is.

You have to address the DEMAND rather than the SUPPLY.

The same in the mid-east. Look at the situations that are creating the terrorists. If you don't deal with the situations, you'll end up with a new crop of terrorists to take the place of the old ones.
