Failing To Stop At Stop Sign
Hello everyone, I got a ticket for failing to stop before entering intersection in Calgary. It was around 1:30 am. Police car was not so close. I did stop but not sure if it came to stop completely. The cop wasn't sure as well I think because he pulled me over not after the intersection but he was behind me at signal and when I switched my indicator for parking he pulled me over. He came to me and said I pulled you over because you missed the stop sign and I have camera recording. I told him I stopped but I thought he might give warning as he was very polite so I told him I stopped but I if you say I am sorry . Then he asked for my licence and registration.
Now 1. How can I ask for the video he has ?
2 . Can he prove that I didn't come to full stop if my brakes lights were on as he was not very close and line nothing visible?
Any guidance would be highly appreciated. Thanks in advance
