Chances are better than 50/50 you will be sued anytime you shoot someone even if you are 100% legal and they have zero chance to win. Even if the victim dies the family will sue you. If there is even the faintest possibity you did something wrong, the odds go up considerably. If you own any property, or have money in the bank the odds go up considerably. If you are working in LE or for a security company the odds go up considerably.
It can cost you thousands of dollars just to win a lawsuit. These people and their lawyers know and understand this. You shoot someone and a lawyer will be sending you papers. Most people have at least $100,000 in liability insurance on their homeowners policy. Your insuance company lawyers figure it will cost them $75,000 to win your case and will often offer an out of court settlement of $50,000 to the guy you shot. This is what they are after. They really don't want it to go to court, because they know they'll lose. But they know it is cheaper for the insurance company to pay out than defend the case.
The more money you have, or if you shoot someone in the line of duty the city/county you work for has more money to go after. If you are poor, and with no insurance, they probably won't bother.
Regrding RN vs HP. Listen to RC. In a 22 the last thing you want is a hyper-velocity hollowpoint. They are going to blow up on contact and give very shallow penetration. A heavier RN bullet going slower will give much better penetration and reach vitals. Expanding bullets work great on smaller game. A 22 HP might be devastating on a rabbit or squirrel, but very likely will only penetrate 1-2" in a human. Not nearly enough to reach vital organs.
