It doesn’t add up to me either, but they could just be really, really stupid. They probably would have gotten away with the robbery if they hadn’t committed an act of domestic terrorism and gotten the fbi involved. Their guns look like they fished them from the bottom of a lake, cut the barrels shorter, cut the stocks off, then duct taped a fleshlight onto the end of one of them. The surveillance pictures I saw of one of the guys looked like he was using a shirt or a towel for a mask, which didn’t even disguise his identity very well at all.
