Can a police officer take down my license plate # and write a report without me knowing? And how can I find out if anything been reported
Criminal Defense Attorney
He will probably have determined (or at least that is what he will allege) there was a tip, suspicious activity, or that you were involved in criminal activity. Police officer's run the plates of individuals all the time. It is usually investigatory. If he is led to then believe you have a warrant or a crime has been committed you may later be arrested. So yes, a report can be generated.
