Get in touch with a local reporter and explain the situation in detail, with as much evidence as you can deliver. Have them attend a meeting. After the article comes out, stand up at the next meeting and state that you were the source of the information in the article...and then sit back down and stay where you are.

Here in NH, you literally have to kill someone to get drummed off a Town Selectmen's council. Not sure how it is where you are, but if you turn on the floodlights and remain in your chair/position, you will shake the shit out of things.
