I Thought Colorado's Pot Law Was Supposed To Stop This

From the Salt Lake Tribune: A 25-year-old is shot dead trying to sell marijuana the old-fashioned, illegal way. Two men from Texas set up a warehouse to grow more than they would ever need. And three people buying pot in a grocery store parking lot are robbed at gunpoint.

While no one expected the state’s first-in-the-nation recreational sales would eliminate the need for dangerous underground sales overnight, the violence has raised concerns among police, prosecutors and pot advocates that a black market for marijuana is alive and well in Colorado.
"It has done nothing more than enhance the opportunity for the black market," said Lt. Mark Comte of the Colorado Springs police vice and narcotics unit. "If you can get it tax-free on the corner, you’re going to get it on the corner."...
Arapahoe County, outside Denver, has seen "a growing number of drug rips and outright burglaries and robberies of people who have large amounts of marijuana or cash on them," said District Attorney George Brauchler.

His district has seen at least three homicides linked to pot in recent months and a rising number of robberies and home invasions.

 Among them was a February case in which a 17-year-old boy said he accidentally shot and killed his girlfriend while robbing a man who had come to purchase weed.
 Elsewhere, prosecutors say, Nathaniel Tallman, 25, was killed during a January drug deal when he was robbed and shot, and his body dumped in Wyoming.
The next month, a dealer mugged three people who were trying to buy marijuana from him in a Denver grocery store parking lot.  http://www.sltrib.com/sltrib/world/57777558-68/marijuana-pot-drug-colorado.html.csp

Anybody who thought that legalizing pot would improve the quality of life of the people of Colorado is quite simply, a stupid pot heads.
People who smoke pot are just a bunch self indulged spoiled brats.  They don't care if they get their pot from a store or from the street corner, they just want their pot.
And many of those people will still act like jerks and some of those will commit crimes, including violent crimes, because they smoke pot.
I am willing to bet that in 5 years or so, Colorado will try to repeal this law after they see what kind of damage it has caused their state.
