Cited for speeding in school zone March 6, 2013. At pre-trial on Apr. 23, filed motion for discovery requesting 6 items. The 3 items most pertinent to my defense were denied to me. How can I still get them? Jury trial is on June 5. If not able to obtain them, can I have case dismissed on grounds that my 5th amendment right to due process has been violated? Items denied me are: 1) PO's notes and comments 2) Total tally of PO's citations for March and 3) Total tally of Police Department's Citations for speed for March. PO's radar gun seems to have last been calibrated June 2012. Only annual calibration required I believe. Will possibly attempt jury null argument based on Police Depts. lucrative, revenue-generating tactics. Any other possible defense strategies advice welcome.
