You would think these DHS 'experts' would game the techniques.
Have paintball guns and the defender has rubber scissors.
Say in the DHS offices. Randomly over a week or two stage an attack and see what works and what doesn't.
I say this cause the idea of scissors against guns was tried in WW2. Only the Japanese had swords and the GI's M1 Garands.
And we know how well that worked out.
