President Trump has said that criminals who kill police officers should be given the death penalty.

Trump announced during a speech for the National Peace Officers’ Memorial Day service on Capitol Hill, an event that pays tribute to law enforcement officers who have died on the line of duty.

“The ambushes and attacks on our police must end, and they must end right now,” Trump said. “We believe that criminals who murder police officers should immediately, but with trial, get the death penalty.

“But quickly. The trial should go fast. It’s got to be fair, but it’s got to go fast. We believe that criminals who murder police officers should immediately, but with trial, get the death penalty.”

He also welcomed the family of Ronil Singh to the stage. Singh was a Newman, Calif., police officer who was shot and killed late last year during a traffic stop by a man suspected to be in the U.S. illegally.

Trump then reiterated that Singh's murder could have been avoided with stricter immigration laws, calling the suspect "a vicious killer that could’ve been kept out with border security, with the wall, with whatever the hell it takes."

In the run-up to 2020, Trump is desperately trying to fulfill his campaign promises.

During the 2016 presidential campaign, Trump said that “anybody killing policemen, policewomen, police officer, anybody killing a police officer, death penalty is going to happen.”

Sixty-three officers have been killed so far this year. A total of 160 officers were killed in 2018.
