@JoeStewart Its fair to blame Nixon as the originator in much the same way that it is fair to blame George Washington for the Kardashians because without George Washington the USA would have never gotten to the place it is today.
Basically Nixon started the DEA, and the existence of the DEA ultimately led to the abysmal state we are in. But the DEA when he started it wasnt the abusive organization in the way it is today, in fact it was quite reasonable at first compared to today.
