Sure if you have all day to argue your rights. If a police officer wants to search your car, either he will or the both of you will spend a considerable amount of time proving a point.......remember he is getting paid for his time. Reasonable cause can simply be your word against his suspicion. If you feel your being truly mistreated, call a cop from a different agency preferably one that is higher ranking (local< sheriff< state police)on your cell and get a second opinion.
I,personally,would like to see *all* cop cars equipped with those dash cams...ones that record high quality video *and* audio.I've only been stopped three times in my life and got only one ticket (which I successfully fought in court) but if I'm ever stopped for *anything* in the future by a cop in a cruiser *not* so equipped I'm gonna fight it tooth and nail on the basis that the cop isn't presenting "best evidence" (a recording) of the incident even though the technology was widely available and the police department could have presented it if they had just spent the $$$.
