Piers Morgan, the resident gun control advocate on CNN, protects his own personal property with signs warning that it is guarded by "Armed Response Security Systems," according to a new investigation by self-described "guerrilla journalist" James O'Keefe.

O'Keefe, founder of Project Veritas, is known for his undercover video and sting operations.

He recently exposed how journalists with the newspaper that revealed the addresses of gun-permit holders in the New York City area were unwilling to take a dose of their own medicine and declare their homes "gun-free zones."

Now O'Keefe has produced a video to expose the double standards of Hollywood celebrities and filmmakers who support President Obama's gun control agenda.

Among those confronted with a request to sign onto an effort to remove all guns from movies was Morgan, who made a brief foray into the top-tier rankings at CNN by badgering guests over their support of gun rights.

O'Keefe's undercover agents approached one of Morgan's Hollywood properties and discovered a sign that said "Protected by Armed Response Security Systems."

The agents also reached out to Morgan on a public street, asking if he would sign an "Act Against Arms" pledge to have guns edited out of past and future movies.

Morgan was willing to accept information about the campaign but would not sign on.

The gun control issue, Project Veritas said, "is being driven by a hypocritical media on the back of a national tragedy."

O'Keefe quoted Obama's statement that if anything that can be done to prevent the loss of even one life, the nation has an obligation to try.

O'Keefe also approached other companies, such as Robert DeNiro's Tribeca Films, and got a few signatures but mostly was rejected.

One filmmaker got irate with O'Keefe, saying, "You're not realistically going to remove all the guns from every movie every made. … Think about what's logically, realistically possible."

Another responded, "All of the 'yes we can' and all of that s*** doesn't mean anything, man."

WND previously reported that police officers themselves essentially are telling citizens they are on their own if an attacker confronts them in their home.

Project Veritas investigators spoke with police officers from North Carolina to New York who told them the unfortunate truth about the time it takes to respond to calls for help and what citizens can do until officers arrive.

Among the comments:

"We try. We can't always get there." – North Carolina

"Sometimes we can't be anywhere at all because everybody's tied up." – North Carolina

"Lock yourself in a bedroom, start yelling and screaming." – Jersey City, N.J.

"Some people have dogs."– Yonkers, N.Y.

"Go get some bleach. Go get ammonia." – East Orange, N.J.

"A rifle and shotgun is actually for luxury." – Kew Gardens, N.Y.

"It's 2013. It's the United States of America. You lock your doors and you hope nothing happens." – New York

The video shows an undercover reporter approaching police departments and asking provocative questions about personal security.

In its probe of the newspaper that exposed the names of gun owners, Project Veritas investigators posed as members of a gun-control group asking to post anti-gun signs on lawns. The targets included staffers of the West Nyack, N.Y.-based Journal News, which published the names and addresses of thousands of pistol permit holders licensed in the Westchester and Rockland counties area north of New York City.

Four times doors were closed in the faces of the Project Veritas investigators, three times the signs were rejected, twice law enforcement was called to remove them from the property and three times they found armed guards already on site.

Stops by the team included the homes of Newark Star Ledger columnist Bob Braun, Journal News publisher Janet Hasson, reporter Alex Weisler, Journal News editor Cynthia Lambert and U.S. Attorney General Eric Holder.

O'Keefe's crew asked the journalists whether they would put a sign on their lawn that says "Citizens Against Senseless Violence. THIS HOME IS PROUDLY GUN FREE!"

Uniformly they were denied permission.
