I would like to see police vs citizens/CCW holders friendly match or something, see how good cops are really. I heard from some high officals from the local PD[taught classes for my college] said they are bad shooters and on average 25-40% good with aim.
SHTF vs TEOTWAWKI you ask? SHTF, just some crap on the ceiling and walls, TEOTWAWKI end of the world as we know it. Orignally made by 9mm/®™©
