I want to put you in jail but you're not doing anything that's currently illegal enough to do so. I know, I'll make up a new crime.
Hypothetical situation: I'm a voter but I hate guns and the people who own them. Guns are a scourge on society. You own a gun but I can't get rid of you for society's sake and I really am thinking of society's sake here. I know, let's tie gun ownership with something else that isn't very serious right now.
Have a gun in your possession when you're caught going 5 mph over the speed limit? Automatic 10 year sentence.
I can think of other ways to just make up new crimes which I can use to throw your ass in jail if you want me to.
Gunnery, gunnery, gunnery. Hit the target, all else is twaddle!
