Hello guys, I was pulled over today for doing 110 km/h in a 60 zone according to the officer that pulled me over. I was going downhill and I pulled over as requested by the officer who was standing in the center lane and stopped the car before me to instruct me to pull over. He then came up to my window and accused me of doing 110 in a 60 and instructed me that he would impound my car and suspend my drivers license immediately. I chose to not say anything as he instructed me to take the keys out of the ignition. As I was taking the keys out, I pulled my window back up halfway which the officer took as an act of agression and resistance apparently and attempted to push the window back down but failed. He then told me to put my hands behind my head during which he attempted to restrain and choke me even though I was complying. He then forced me out of my vehicle and put my hands behind my back but then let me go and instructed me to follow him to his cruiser. He then told me that he would not impound my car and he would let me keep my driver's license by dropping the 110 km/h to a 109. He explained that he thought I was trying to escape by putting my window up. I explained that the car was already in park and that my intention was not to go anywhere. I then took the ticket and left. I believe that the officer's behaviour was unconstitutional and his misconduct was not necessary. I also understand that a charge of 30km/h and below 50 carries an application of 4 demerit points and the charge itself will increase my insurance. My record is clean and I was wondering how to proceed with this. Through some research through Google maps I found out that the stretch I was stopped in was a 70 km zone not a 60 as according to the officer. Should I request a first attendance meeting or outright fight it? Any advice would be appreciated. Oh, and I carry a G2 license. Thank you.
