Wait, what the fuck are people talking about the DEA in the 20's when it wasn't even founded until the 60's under Nixon's administration. Also, I don't agree with their "marijuana eradication" operations at all, but they also do work against cocaine, heroin, and meth cartels-WHO ARE FUCKING SICK. Just look at all the killing south of the border now. It should be noted that this killing is happening because the DEA and mainly border patrol are seizing more dope than usual causing the cartels to get more agressive and violent, but IMO this is off set by the fact that these aren't marijuana traffickers they're bringing in the hard shit. And if they are bringing in marijuana, they're still violent as fuck.
The DEA has alot of flaws but I think it's nessecary for someone to check these cartels until the US takes more serious legislative steps to end the war on drugs and get better help for addicts of hard drugs. If the DEA only supported a "War on Cartels" and not a "war on Drugs" I'd support them fully.
I like the show alot, but I swear to God if some of these guys weren't slightly sociopathic cops than they'd be totally sociopathic criminals.
