Depends what your definition of "security system" is

I'm not sure if people are following what happened at Mount Rushmore (a place I've been twice - it's amazing and worth the trip), but it's gotten pretty out of hand. People are wondering, naturally, how the Greenpeace folks were able to climb the mountain and unfurl the banner asking Obama to more strenuously combat greenhouse gases. Well, it sure wasn't a security breach!
“All security measures functioned exactly as designed,” said Memorial superintendent Gerard Baker, reading from a prepared statement Thursday morning. Baker said park officials would review security systems and procedures in light of the incident. There was never any danger to visitors at the memorial, and programs continued uninterrupted, he said.
Huh? That was from last week, though. Surely they've changed their tune by today? Not so much.
Mike Evenson, district manager for SimplexGrinnell, said his company hasn't received any requests for service of the system from memorial officials. "To my understanding, everything worked as they expected," he said. "We did not have any reports of anything that failed or did not work as they designed it."
Well, then, what happened? They saw the Greenpeacers heading up there and didn't care? Is that the implication about the "danger" part of the first quote: "We saw they were there, but we knew there were just banner hangers, so we let them do their thing and then arrested them. Easy-peasy. If saw guns, or didn't see a banner or something, we'd have been all over them with helicopters and machine guns." It's hard to know.
Matt Leonard, one of the climbers, said he didn't see any cameras or other security measures on the hike up in the dark. He believes the holding area where the climbers waited, just 100 yards from the faces, was not monitored by security cameras. Only when the Greenpeace team got very near the sculpture did Leonard notice the fences and cameras.
Looks like Rushmore didn't have a way to extend its perimeter. This goes back to something the Israelis always wonder about American security systems: If the first time anyone encounters a security system is when they're at your front door, what stops them from walking up to your front door and blowing up your house? Nothing. So why are metal detectors INSIDE buildings? I also like how the Greenpeace folks come to the defense of the security guys:
It would be hard to make any security system foolproof in such a rugged terrain, said Michael Crocker, a Greenpeace spokesman. "In fairness to the park officials there, it is a massive place. And they have limited resources for that (security)," he said. "Obviously, we were able to get around it."
Being pitied by Greenpeace: Is there a more embarrassing moment for a security guy?
