My question involves a speeding ticket from the State of: California

Thanks for taking a peek at my case :-)
Got a ticket on I-50 - Sacramento Area - Speeding. Officer wrote I was doing 90 in a 65 zone but I was doing 80-85. Went to the court pleaded not guilty and asked for Trial.

The DA asked me to plead guilty with a lesser fine and traffic school opportunity and I refused. So the DA checked the officer's schedule and made a note on the file that the officer involved was on vacation from March-15,2010 (Monday) to March 25,2010. The clerk was about to assign a date and I requested March-12, 2010 (friday) 1:30 PM for the trial.

On the trial date, the officer didn't show up. The DA wanted to talk - mentioned that there was a clerical error - said the officer was on vacation - wanted me to reschedule. I asked the DA to check again - he goes inside and comes back with many more vacation dates. When my came up for trial the case was not dismissed since the officer was not there.I was asked to pick a date and come back again.

My Questions:
1) I think the DAs lied/screw-up here. What is the procedure or paperwork to check/prove that?
2) When the Officer didn't show-up, can the DAs reschedule? Is it a law that if the officer doesn't attent then the case should be dismissed?

Thanks again
