"President Obama and Mayor Bloomberg are pushing gun control. But America's police say they're wrong," a narrator says in the ad. "Seventy-one percent of the police say Obama's gun ban will have zero effect on violent crime. Eighty percent of police say more background checks will have no effect. Ninety-one percent say the right answer is swift prosecution and mandatory sentencing. Tell your senator to listen to America's police instead of listening to Obama and Bloomberg."
