My question involves traffic court in the State of: California
Will objections during an officer's testimony or the cross examination between the prosectuor and the cop be frowned upon in court? Might sound like a stupid question but... is that allowed? I plan on interposing hearsay objections when the officer says things like, "the traffic engineering survey is up to date", "I am certified to operate radar", "The radar was tested and calibrated", etc. Can those motions be denied even if he doesn't produce the documentation?
