guess im innocent and get to walk scott free

Assuming no one saw you murder the AFK player (you didn't mention that part), yes, you can walk away. No one has proof that you weren't hit with a crowbar. If you report whoever kills you, and the logs don't match what you're saying, don't expect the person who killed you to be slain because you lied.
