Hmm... I wonder why that LEO is carrying two Mini-Uzis?
Also in the second to last photo, the H&K MP5 is a ASP "RED GUN". Those are training aids. They are made out of a hard rubber/plastic compound. Weigh just about the same as the real firearm expect no moving parts, bright color to let folks know it's a training tool, and lastly very hard to break. Oh, before I forget it also cost only $45.00 US.
(There are stupid folks, they see me train with a ASP RED GUN and think and ask me if it's real.)
