To be honest - I have no clue who to believe in this saga. I have looked at the video and have seen no indication that the cops where doing anything unlegal. They brought out the dog which is looking for drugs and then they arrested you. Maybe you are right and it is a big conspiracy - but maybe not. I will never know.
BTW, it is normal that you are not getting a pen and a piece of paper but have access to a smart phone?
