Fighting a speeding ticket... questions

[SLaP]

I am doing some research regarding fighting speeding tickets.

Any answers you have regarding any of the questions below would very much be appreciated. If you have sources for your answers, please provide links, contact information, etc.

1. If there were 2 police officers present at a speed trap, one sitting in the car, while the other gunned and ticketed drivers, do both officers have to show up to the court case?

2. What is the common radar/lidar device used by 63 division? Are they using more than one type currently?
Links to manuals?

3. Are the any cases in Ontario which have proven that a hand-held lidar device is subjective to the officers hand stability and proven to be inadequate to provide an a correct reading? Please provide details.

4. Although it is unlikely to receive the information regarding the other stops for that day, has anyone or their agent, been able to receive this information in the disclosure?

5. Although it is unlikely to receive the information regarding the number of over-time hours the officer has logged in a given timeframe related to traffic infractions, has anyone or their agent, been able to receive this information in the disclosure?

6. Can one (and should one) apply for disclosure prior to the first appearance?

Thanks in advance!
