WASHINGTON - May 14, 2009 - An April 7 report from the Department of Homeland Security branding some conservative groups as “right wing extremists” is enough reason to revive former President Bill Clinton’s idea of an assault-weapons ban, according to an executive of a gun-control group - the Brady Center to Prevent Gun Violence.

"I think it certainly helps to make that case because what that report suggests is that there is a rise in the kind of paramilitary activity that we saw actually in years before the Oklahoma City bombing,” Dennis Henigan, the vice president for law and policy at the Brady Center, told CNSNews.com Wednesday.

Henigan talked about the years before the 1995 Oklahoma City tragedy - when “right wing extremist militia groups (were) out training with assault weapons, training for war against the United States government, training to shoot federal law enforcement,” he said.

"Now, unfortunately there is very credible evidence that that is beginning to happen again,” Henigan added later. “So, there is no place on our streets for these kinds of military weapons.”

He described assault weapons as being “designed for war,” adding that, “they are designed basically to kill as many people as possible, as quickly as possible in a battlefield situation.”

Henigan spoke to CNSNews.com after he testified before a House subcommittee on Capitol Hill in support of the No Fly, No Buy Act of 2009, sponsored by New York Democratic Reps. Carolyn McCarthy and Steve Israel.

Neither McCarthy nor Israel answered inquiries from CNSNews.com to comment on Heinigan's comment.
