Color me shocked. These weapons are already in the hands of some crack dealing gangbangers in Chicago.
Certainly sounds like an inside job.
Leave a cache of weapons at an unsecured location not equipped to store weapons and surprise, surprise they come up missing.
Who ever signed out those weapons from the weapons master should be investigated and be sent up for as long as possible.
The weapons master needs to be investigated as well. He did not report the weapons not returned. If he was ok with the weapons being stored in that trailer he needs to be locked up as well.
