Meanwhile, right here at home there are fresh grounds to wonder about federal security efforts.

The Post reported Tuesday that airline passenger Berna Keiler, who has a 14-inch titanium rod in her hip, passed through metal detectors at JFK twice last year without triggering alarms. On Wednesday, Post reporter Lorena Mongelli carried a titanium chain through the detectors without notice — also twice.

Titanium, by the way, is often used to make weapons — including handguns.

The Transportation Security Administration’s response to these failings?

At JFK, “all walk-through metal detectors were tested,” TSA aide Ann Davis said, “and successfully passed.”

Ah, we get it.

The system is working.

Feeling safer yet?

We’re not.
