Bleh. From the BBC news on Mexico:

The latest violence came shortly after Mr Calderon told the BBC the US should do more to reduce the demand for drugs that is fuelling violence in Mexico.

He told the Hardtalk programme that more should also be done to stem the flow of illegal weapons from the US.

President Calderon and other regional leaders have urged Californian voters to reject moves to legalise marijuana in their state.

Last week, police in Tijuana destroyed 134 tonnes of cannabis - the largest drugs haul ever seized in the country.

Local reports said most of those killed in Wednesday’s attack were recovering drug addicts who worked at the car wash.

The cartels have targeted recovering addicts before; observers say the gangs accuse the rehabilitation clinics of protecting rival dealers.

Police believe drug cartels use the clinics to recruit hitmen and smugglers, threatening to kill those who fail to co-operate.

IOW, Calderon is blaming the USA for arms dealers and drug users. So if they legalize pot in California he thinks things will get worse in HIS country.

BTW, I happen to have a suspect that the “134 tonnes of cannabis” haul was a publicity stunt.
