It's better to be in prison unjustly than get killed for making the supreme mistake of grabbing a gun when you are being arrested.
The problem being, if you have no reason to expect a police raid, people yelling "get on the ground" after they kick in your door tend to alter your perceptions of what is the better choice. Hmmm, do nothing and get killed by home intruders, or grab my gun and defend myself? I guess I'll just be a sheep...
