No, not all police officers have backup. In THOUSANDS of shooting situations, they are by themselves. And the weapon used by the OVERWHELMING majority of police officers is their SIDEARM---which just happens to be a semi-automatic pistol in virtually every significant police department and law enforcement agency in the country.
Funny, but the police haven't found semi-autos to be unreliable at all. The overwhelming majority of street officers with NYPD, LAPD and other major police departments around the country---have a STRONG PREFERENCE for the semi-auto.
It was the officers in the street who fought "city hall" for years, over the right to carry semi-autos. They were just plain outgunned while carrying revolvers, and officers were dying in shootouts with criminals packing semi-autos.
