I'm curious as to how they actually did it. The article mentions they went disguised as cops, but when cops take a stash house they don't knock, they do a raid. Kick in the doors, clear the rooms etc. And these days PDs have SWAT teams out the ass, so usually a SWAT team would pull stash house duty.

It also seems that they were doing it for quite a while. In all that time word didn't get around among the drug gangs that a handful of "cops" are kicking in their doors and leaving with their product but never arrest anyone? It seems weird that no one ever shot at them during a robbery or tried to go after them later...
