White knights everywhere.

And you're wrong. Eric Garner got riled up and the police over-stepped their bounds. I've interacted with police many times and never even had a heated engagement. You'll never beat the police by losing your temper. The only way to handle the situation without getting yourself all sorts of messed up is to just stay cool. Comply and be cordial, then if they've violated your rights sue the ever-loving shit out of the precinct. Say you shoot first, yay, you've killed one LEO. What's the next step in your genius plan? Do you honestly think people will miraculously band together and stop the police from hunting you down like a feral beast after that? You don't respawn and you don't get backup. Meanwhile, you've provoked every LEO within driving distance and become the prime target for people with a lot of experience in violence, nearly unlimited funding, and no societal net holding them back from achieving their objective at that point. Meanwhile, you're on the complete opposite end of the spectrum in every aforementioned possible advantage.
