Understanding US Gun Usage Rules

Citizen rules :

1. If an MMA expert is pounding your head into the pavement trying to kill you, you are not allowed to use your gun to defend yourself.
2. If someone is breaking into your house, you are not allowed to follow the Vice-President’s advice and fire a warning shot.

Government rules :

1. Police can try to kill you, if you are driving a blue pickup truck
2. Police can kill you for bringing a flashlight to the door
3. Police can kill you for stepping out of the house when your neighbor’s burglar alarm goes off.
4. FBI can execute you, if you don’t give them the answers they want

The government has some advanced C++ software for reviewing police killings.
