They call me graland.

I'm interested to know how exactly this system is foolproof when scanning for guns. Interesting idea, though:The holidays may have provided a temporary distraction from the Newtown, Conn., massacre, but now that the new year's here, it's time to pick up where we left off. Here's one security company that thinks they have a way to prevent a dangerous intruder from entering a school or any other building.

It called the Linear Revolving Door (LRD), and it was recently patented by Barbecan Security Systems. The door consists of series of parallel hallways that can be built at the entrance of buildings. Each hallway has two doors that revolve in front of and behind a person as they enter.

The system is equipped with sensors that keeps pace with one's stride to cut down on the bottlenecking of most security checks. Once both doors close, sensors also check for bombs or firearms. If a threat is detected, the doors move in reverse and push out the potential offender.

Check out this animation to see the LRD in action. Though beware, it's quite hypnotic.

With statements like "Newtown could have been prevented," Barbecan's press release is confident, if not cavalier.

"A guard at a building entrance won't stop a determined and well armed attacker -- especially if they have suicidal motivations," it states. "The LRD portal WILL NOT let an armed gunman enter a building. Period. When a threat is detected, the portal reverses and the potential assailant is backed out of the portal. Gun control is not the answer."

While some parents of Sandy Hook Elementary school children might beg to differ about that last statement, Barbecan contends the LRD is the new solution that's needed.

"Operation is completely safe," states the press release, "and by adapting to the pace of pedestrian traffic, LRD Portals can be used in high traffic entrances like schools, malls, theatres, stadiums and factories."

Stop banning me please.

All that would do is prevent escape

Yeah i see this giving false positives and constantly pushing kids out and all the BS like at airports.
Maybe we should figure out what the root of these crazy people are. Is there some sort of traumatic experience or social situation where people are being traumatized, can we help them instead of treating everyone as potential criminals?

It won't happen.

It would violate nearly every fire code in the US.

Fire alarm? Other kind of evacuation? OPEN ALL THE DOORS!

Being an automated computerised security system, it's pretty -blam!- obvious that they would program it to fully open in case of emergency evacuation. And in practice it likely (shouldn't) wouldn't be unmanned as an armed guard should be around to make sure it's in working order and to observe things. Other than that I have no idea why this can't be a replacement to metal detectors.

There is nothing you can do to make schools more secure by installing hardware that doesn't make it a fire safety nightmare. Measures such as these, or bullet proof glass really only work on things that are occupied by armed guards capable and willing to use deadly force, or on things that move. If you make something too much of a fortress, they'll just wait outside during a fire/fire drill and accomplish the same goals.

Instead of pissing money into making schools more physically secure people could a) stop taking manic, ferocious dumps all over people who are socially outcast b) stop applying a stigma to mental illness c) focus on mental health treatment.

More guns would solve school shootings

  • 01.06.2013 3:42 PM PDT

Well, spending millions to install high-tech security equipment in schools and paying technicians to fix them whenever they malfunction certainly seems easier than changing our lenient gun laws.

Which defeats the purpose of the entire system... All you need then is a have a buddy get in, pull the fire alarm, and let the shooting commence once they are all outside.

There is potential, but I don't see it working,

Edit: Where would the money from this come from? The education system is bad as it is, shouldn't money be spent on, I don't know... improving education, not security?

Yeah, it's awful this happens, but it's not a common occurrence.

Why doesn't every terrorist just go and do that at an airport, bank, government building, wherever?

This could be put in more than just schools. It would make more sense if it was put in an airport tbh.

1. Cost
2. I would rather it lock someone in then reverse the person out for them to vent on the people outside.

Sure, mass transit junctions makes sense, just not every school across the nation.

And they don't because of the high security presence... and low chances of success.

Can imagine this in a subway in the future with fancy glass screens saying SCANNING as you walk through. -blam!- futuristic -blam!-.

Sounds like something you'd see in an Airport, not a freaking elementary school.

Case and point: don't worry about it. Girls start getting boobies pretty soon, and then you'll have plenty of other things to think about. Being an Inheritor is not a life goal.

That's my thought. This can only go so far to prevent a threat, it doesn't make it impossible.
