Where I live, anyone trying that would simply be shot. Robberies (esp. with knives) aren't so common here in states where you don't know who's carrying a gun. But I guess in states or countries where you're not legally allowed to defend yourself, that could be a problem.
Yes robberies in the states with knives are not common. Since weapons are so easy to get here in the states our criminals have them more than the people who can legally possess them. In the states you get robbed and gun point and most likely shot as well.
