Homeland Security has advice for confronting mass murders: scissors

◼ That’s some of the helpful advice in a new instructional video from the Department of Homeland Security that was posted on the agency’s Web site just a month after the massacre at Sandy Hook Elementary School in Connecticut. - S.A. MILLER/NY Post

The nearly four-minute-long video opens with chilling scenes from the 2007 Virginia Tech massacre, the 2009 mass shooting at Fort Hood in Texas, and the 2011 attempted assassination of Gabrielle Giffords.

But the video quickly shifts to hokey footage of office workers scampering under desks, crouching in corners and racing into closets to hide from a rampaging gunman on the loose.

“To protect your hiding place, lock the door if you can. Block the door with heavy furniture,” recommends the male narrator, speaking in measured, authoritative tones.

Other survival strategies promoted in the video include hiding “behind large items such as cabinets or desks. Remain quiet. Silence your cellphone or pager. Even the vibration setting can give away a hiding position.”

Richard Feldman, president of the Independent Firearm Owners Association, said he has a better option for consideration than a pair of scissors when confronting an armed mass murderer — a legal firearm.
