I agree, but that's only if we included tobaco and booze.
Executing drug dealers only assures that only the most ruthless, reckless drug dealers, with the firmist grip on legislatures and law enforcement though bribery and intimidation will be selling drugs to our kids. In no other realm of discourse but this one, is the notion that supply drives demand taken seriously. If increasing the penalties drives away dealers, why hasn't it done so here in the last 80 years?
There was one year in this century when the violent crime rate, in one year, sunk to a fraction of the previous year. It was the year we ended prohibition. This is also the last year that reporting of instant rotgut-induced blindness was daily newspaper fare.
If you don't give turd what happens to children (which is what I suspect), than by all means, execute drug-dealers.
