Peter Christ is a former Police Captain. Here, he makes a compelling argument about how the "War on Drugs" has failed, and needs a major overhaul.
Definitely worth a watch. Christ isn't so much being all like "drugs, yo!" as it is an economic and moral argument. He discusses the tragedy of impoverished opportunism, and the harsh realities of the illegal marketplace that would arguably be significantly better off/better protected And furthermore, how the tenants of law enforcement become a bit warped, leading to mistrust between police and the general public, particularly the in relation to the lower class.
Much of what Christ discusses is echoed in Eugene Jarecki's recent documentary "The House I Live In," which talks about the same shit in a much more investigative matter. All in all, this is some real, not just in "The Wire" shit that's profoundly affecting how we operate on a larger institutional level.
