The long-suppressed videotape detailing with what one police officer called “a routine traffic stop” four months ago finally saw the light of public scrutiny Tuesday night. The tape was from a police patrol car dash cam which recorded the exchange between county legislator Jennifer Schwartz Berky and officer Gary Short in the Town of UlsterBerky’s lawyers sought to suppress the dash cam on the grounds that it would compromise her chances for a fair trial.Short returned and offered to write a ticket for failure to wear a seatbelt, a much lesser offense than speeding. Berky told him she always wears her seatbelt and refused the offer. Short then wrote the speeding ticket.
