All you're doing is drawing attention to yourself. Writing a letter won't do anything but get the cops called on you (obviously)

You don't have to be afraid of police, but there's also no practical reason for running your mouth about how not-afraid you are; it's just going to upset them and make you a more visible target, and it WONT ACTUALLY CHANGE ANYTHING (obviously)

If you want to make a difference, help your fellow nonviolent citizens to improve their quality of life on a local, individual level. Even though your ego might get in the way, it would serve you well to try to lay a bit lower.

Not that you have any chance for anonymity now that you've been pinned on GLP for making the cops think you're a terrrrrrrist hahaha
