Some of you have difficulty with your comprehension skills. I was followed initially, followed repeatedly, and then and only then was an expired registration discovered. The officer sped up ahead of me, threw on his lights and sat on the side of the road waiting for me to pass. I was not speeding. Why was I pulled over at all? Anyone answer that one? Yet, many people that have commented here continue to insist that the officer has the right to pull me over make up a speeding violation, and then subsequently bust me for no reg. WRONG. This is called RETALLIATION for having called and complained about following me repeatedly to begin with. Thanks for your ignorant criticisms. I'll let you know what a judge says and I'll let you guys know how much money I get when I sue the department for harassment. Keep thinking the way you do. Have fun.
You might want to do some research into the statutory requirements for a harassment suit. Police arent harassing you when you are violating the law. Even without the registration issue you have not laid out a pattern of offenses that is egregious.
As to the initial following, there may have been a BOLO identifying a similar vehicle. Also you left a bar after midnight and there is nothing improper when an officer follows you to relieve his suspicions.
What did you think you were going to accomplish by calling the police dept?
