Well think of it this way, I am sure law makers and law enforcement don't have to use them so it's no bother at all.
I get panic attacks, can you imagine if one of those things accidentally locked on me?
Who is going to take the blame when people are looked in during a shooting? What if the power goes out and there is panic? I hope there are other fire exits.
If it was designed with safety in mind, it would probably need power to stay closed. If there is no power it would prop open. But then, I got stuck in an elevator for an hour last month, so yeah, people would probably diaf.
I suspect it's a reaction to the LAX shooting to prevent an attacker from fleeing on foot so easily - similar to the double bank doors you sometimes see on banks in dangerous countries. More important than proper fire exits? No. Just my theory on the possible purpose.
So keep the gunman locked in with more people around them to shoot?
While the LAX shooting was happening I kept wondering why the shooter didn't just go backwards through the exit. There is usually just one (half asleep) agent sitting there. This would certainly prevent this.
TSA quit screening my thoughts!
And everything I said is just wrong, before there is no check for living the restricted area.
