A California police officer was recently killed by an illegal immigrant and his boss, the sheriff, sounded off against California’s sanctuary city policies.

According to The Daily Wire:

In an interview with Fox News on Thursday, the officer in charge of investigating Singh’s murder, Stanislaus County sheriff, Adam Christianson, drove home the connection between Singh’s murder and the issue at the forefront of a Congressional budget battle.

“Because I want the nation to know, I want your viewers to know, that Officer Singh really should be the focus of this investigation and his sacrifice. But I also want everybody to know that immigration is good for America, if done legally. Illegal immigration doesn’t serve our communities, especially criminals who victimize and exploit our communities,” Christianson told Fox.

“Whether you hate the president or love the president, border security goes hand-in-hand with national security, the safety of our communities, and public safety. We need to know who is in our communities that shouldn’t be. We should be focusing on criminal activity without political interference,” he continued.

He repeated his criticisms in a press conference on Friday announcing Arriaga’s arrest, slamming California’s “sanctuary state” laws that prevent law enforcement from prosecuting and deporting illegal immigrants captured during routine law enforcement actions.

A total of eight men have been arrested in connection with his death. This is another example of the needed change to the country’s immigration laws.
