So, a robber walks into a store... and Judas Priest starts playing

Hitting the robber across the width of his body with the width of the chair top, if the robber had a knife pulled, well it's not as effective as swinging the top of the chair, edge on into the base of the neck - execution style. Armed robbers = Fuck them.

Could you make out what the robber was armed with?

@Life_N_Times_of_Shane_T_Hanson: No, I'm guessing that it was a knife!
