Of course, you need to blow the safe with a bomb (where you buy or make from a place that I don't care), and plant it, you will need it 5 minutes to blow the safe; enough time for the cops to come and kill / arrest the robber. If the robber dies the bank is scured (unless a civilian kills the robber he becomes the robber just incase there was an accidental teamkill)
