>>8751063Modern day police can get away with just one, since they're usually up against unarmed people. You want 2 for block, guard, and counter against knifes, swords, and polearms.
It really should have been 2 ninjatos, 2 axes, 2 tonfa, 1 of each nunchaku, and a few throwing stars/kunai. Did the Foot even use sais in the movie?
