Since the blade snapped off in his leg, I don't think I will recommend a folder brand that self-destructs to anyone. Even my Edge would not have snapped like that (don't even think my Leek would have). I have a problem with that scene anyway. The "mindless" infected (zombie?) has enough IQ to move the mannequin, enough IQ to rig a rope snare just like the Colonel's, enough IQ to bring 3 infected (but still manageable by him) attack dogs to handle the Colonel's dog, but not enough IQ to simply shoot the Colonel from the doorway, or blast him from one of the abandoned Bradley's sitting on every corner? Not even enough IQ to use fire as a weapon against the house, but enough to rig a rope snare with a taxi as a counterweight?
