The police (UK) put my cuffs on real tight?

Hey, police are sooo harsh sometimes! I think some police officers actually enjoy the drama of hand-cuffing tight and causing pain people. I've been arrested before for same thing/s and I have been treated exactly the same. The way they cuff actually causes bruises too! Which is not nice. Yeah, its bad to get arrested and we should learn from that but I don't think being hurt by cuffs is right?? despite what you've done shouldn't have to have bruised wrists and marks. Nothing we can do though! :/ hope they aren't causing too much pain hun. cheer up :) xx
