Via RGJ:

Officials of the Nevada Department of Wildlife report a "tremendous increase" in illegal marijuana cultivation on public land in recent years, with much of the activity associated with violent Mexican drug cartels.

Republican presidential candidate Rick Perry has said he is open to the idea of sending the US military into Mexico to fight drug cartels:

“It may require our military in Mexico working in concert with them to kill these drug cartels and to keep them off of our border and to destroy their network,” Mr. Perry said during a campaign appearance here.

Meanwhile the activity that does happen north of the border, to supply a relatively innocuous substance to a market with no signs of decreasing demand, is increasingly impacting regular people not accustomed to dealing with armed criminals.  Back to the RGJ:

Such incidents by those recreating or working on public land are dangerous, with many growers likely to turn violent, Buonamici said.

"These people are not even in the mindset of dealing with someone who is armed and dangerous and may use deadly force," Buonamici said. "The stakes are pretty high for the folks involved in these grows."

Prohibition is not working.  Production, distribution and consumption of drugs will continue.  Criminal gangs will grow ever more violent.  They will seek to occupy whatever out of the way locations they can find to cultivate marijuana.  That could be the house next door, it could be the national forest down the highway a ways.  People will still want to smoke the stuff.

Rather than spend all the law enforcement resources trying to stop this kind of thing from happening, we should instead stop it from happening in the most logical way:  legalize the cultivation and distribution of marijuana.

Problem solved.
