Former Gov. Arnold Schwarzenegger (R-Calif.) says Americans must be more vigilant to help law enforcement prevent terrorism following the mass shooting last week in San Bernardino, Calif.

“We all have to kind of be cops here and be a little more vigilant,” he told France 24 English on Tuesday during a visit to Paris, the site of coordinated terrorist attacks in November. "Then we can get the job done and reduce the violence."

Schwarzenegger said that terrorism was becoming a more common danger.

“It’s without any doubt a new era, and I think we just have to be very vigilant now. I think that government alone cannot solve this problem,” the Hollywood actor said.

“I think when people become much more alert, [they should] watch and when they see something unusual happening, they should report it to the police."

The attack in San Bernardino left 14 dead and 21 wounded.

The FBI announced Monday that the two suspects in the massacre were likely radicalized Muslims.

“We have learned and believe that both subjects were radicalized and have been for quite some time,” said David Bowdich, assistant director of the FBI’s field office in Los Angeles.

The suspects — Syed Rizwan Farook, 28, and his wife, Tashfeen Malik, 29 — died during a shootout with police in nearby Redlands, Calif.

The incident has stoked fears that the Islamic State in Iraq and Syria (ISIS) will inspire attacks on American soil. ISIS boasted on its official radio station last weekend that it considered the couple “supporters.”

“We pray to God to accept them as martyrs,” the terrorist organization said, though it stopped short of endorsing the pair as full affiliates.

Reports emerged Tuesday that investigators are now looking into a suspicious $28,500 bank deposit Farook received two weeks before the attack.

Schwarzenegger is in Paris this week lobbying for global restrictions on carbon emissions during the COP21 climate conference.

He said Tuesday he hopes that terrorism does not distract world leaders from addressing with the negative effects of climate change.

“The important thing to recognize is that while we have these tragic moments, and while you see it in the news all the time, you should never forget that every day we have 19,000 people dying of pollution,” the former California governor said.
