It matters if the 5'2 guy was raping or abusing children and now complains someone is doing the same to him. Or if the little guy raped women, or killed people --- then what does he have to complain about?
Yeah, you describe an extreme situation, and in this case the guy's treatment in prison might be a poetic justice. Honestly I'd have a hard time protecting his sorry skinny little arse if he had been a raper of kids - especially if he'd done this to my wife or young daughters. If I caught someone in the act doing something like this to my family, I'd be inclined to shove a broom stick up his ass... and then call police (maybe). But there's a small chance that he actually did this. And it's still unconstitutional. We claim to be a nation of laws formed under the watchful eye of a Constitution that protects our God given rights. It's the extreme situations that challenge our resolve, and extreme situations often provide the excuses that liberals use to bend the laws to their liking.
