A key factor here in the intervention and capture or identification of a weapon before someone comes into a facility is really acknowledging what the spectrum of potential weapons could be. You have to be able to understand what they could be, such as metallic or non-metallic. A switchblade would be an example of a clearly metallic weapon.
The bigger concern is where we are seeing a lot of trends going right now, and that's to ceramic or composite-type weapons. There's the advent of the additive manufacturing gun. That's coming into play now. It's sad to say, but that's the reality. Perhaps of special concern is any kind of explosive or that type of substance coming in. It doesn't take an awful lot.
