I was reading THINK DEFENCE blog and got down to the comments section when when of his readers suggested this WIRED article.
Long story short. Blame the DoD for the militarization of the police departments all over the US. Instead of donating gear to allied nations that desperately need it (like the Philippines fighting terrorist on their islands...or even Malaysia that's doing the same).
What does this mean for the future? A bigger appetite for military grade hardware by police, a quicker shipment of that gear while the US military sheds equipment...a deadlier confrontations between police and citizens.
