Chelsea, Oklahoma Roadblocks

I just went to town to wash my car and was detained for over an hour. They asked me over andy over about illegal drugs, firearms, if I had any warrants, etc. Drug dog was sent around my vehicle, vehicle searched and had to do a sobriety test. I had done nothing wrong and they had no right to treat me the way they did. I have never experienced anything like this. I now know my rights regarding road blocks and this will not happen again. Thank you.
