Police is taking down my pro Palestine flyers

My pro Palestine flyers that I've put up on public billboards, after I've confirmed that I'm allowed to put my own flyers up there, have been repeatedly removed over and over gain. Turns out my local police department is doing it. I've even seen an officer taking pictures of me and calling for backup. So much for 'Murican freedom of speech. US police are fascist insects and genocide apologists.
