Do you think that cartel leadership would view any such thing as being counterproductive if the law enforcement agencies were not militarized?
The cartels have long been wary of US armed response to their actions, and the militarization of the police in the US, while certainly a further deterrent, is much closer to a deterrent against CIVILIAN misconduct and works insanely well as a chilling effect against protestors and unruly gatherings. Yay America!!!!
