So you're out shopping or just picking up a coffee at a local mini mart and man attempts to rob the store. 1. You're carrying, you're alone (there are others in the store but you do not have any loved ones with you) the robber does not show a gun but has a knife pointed at the cashier. What would you do? 2. Assume all circumstances are the same as above but the robber has a gun pointed at the cashier instead. What would you do? According to different state laws can you legally do anything?
