Former NYPD officer Dan Bongino blasted U.S. immigration policies after a police officer in California was fatally shot by an alleged illegal immigrant fugitive.

As Fox News reported, Gustavo Perez Arriaga is accused in the shooting death of Newman Police Cpl. Ronil Singh.

Singh was gunned down last Wednesday after he stopped Arriaga for a DUI investigation, Sheriff Adam Christianson said at a Thursday news conference.

Bongino said on "Fox & Friends" that Singh -- who legally immigrated to the U.S. from Fiji -- was "everything that's right about this country."

"This hero should be alive right now. He should be alive right now, and we lost him," Bongino said.

As of Saturday, eight total suspects have been arrested in connection to Singh's death, including Arriaga's girlfriend and brother.

"A guy who should not have been in this country was here, because we cannot defend our borders, because our politicians in D.C. aren't doing a damn thing about it," Bongino added.

He said that Singh's murder won't change the minds of open-borders advocates in California.

"I think that there is a ... substantive wing of the Democrat Party that is absolutely committed to open borders and basically the destruction of the Republic as we know it," he said.
