The Weaver story is a tragedy. If the FBI HRT sniper fired outside his rules of engagement, then he should be prosecuted. Apparently, no prosecutor has found lawful grounds to proceed with a murder prosecution. Like it or not, that is the judicial system we've all agreed to abide by through our societal contract with our fellow citizens. Police officers fire to stop a threat.
Military personnel shoot to kill.
Most cops do not ask for, nor expect, rewards for performing their duties. I happen to know that many police officers take the thanks they receive from the public as their only reward. You state that you can take care of yourself, thank you very much, and don't need a police officer to protect you. A police officer's function is to protect the rights and lives of those who cannot protect or defend themselves. And what's more, I'm sure they'll come to help you despite the animosity you hold for them.
