A gang comes to your place of business with guns. Its leaders tell you they will protect you. You don't want them to do this. They insist and by force remain in the area and demand that you pay them. You don't want to, but in order to not be encaged or attacked, you pay them so that you obey and pay them so you can go about your business.

Is it moral for the gang to do this? Would you object to their doing it?
