For example, for a while most prostitution and sex work seemed to be online, on places like Craigslist right next to ads for used furniture and jobs. And it seemed to be really effective in getting prostitutes off the streets.
Now that those markets were shut down, I'm seeing here in Seattle we're having pimp shootouts on Aurora and the prostitutes are more brazen than ever. Going after Craigslist has had a negative effect on our cities and has increased crime, and I suspect going after SilkRoad has had a similar impact.
I would much rather the police be focused on stopping violent crime rather than these victimless crimes.
Legitimizing drugs/prostitution makes is easier to regulate and ultimately make safer. Shoving this stuff into a black/gray market is what ultimately creates violent crime.
The inflow/manufacture of narcotics won't be affected at all. You'll still have a constant new influx of junkies, and it you'll essentially by funding this widescale and expensive solution forever.
Much better to simple make drug trafficing and manufacture a capital offense. It's been extremely effective in a lot of jurisdictions. Even if you're squeamish about the death penalty, a back of the envelope calculations will tell you you're saving a lot more lives than you spend due to decreased overdoses, drug wars etc,
