Yes, and this is possibly the biggest problem with TSA.

After Pan Am 103, we did not ban electronic radio/cassette players
After the successful and lethal test (liquid-based) bomb in the Bojinka plot, we did not ban Casio watches or toiletry bags let alone water.

I know some if not all of these bans were considered by security forces, but common sense prevailed, and no permanent bans were introduced. Those threat vectors remain viable, but the perpetrators were dealt with (somewhat) and society moved on.

Once TSA was created, common sense went out the door and every new threat "required" new, permanent, and traveler visible (to maintain the security theater) restrictions. (shoe carnival, war on water, NoS, genital grabs)

The first (and only that I know of) hint that sanity may have returned is that DHS Secretary John Kelly failed in his very strong 2017 drive to institute a total and probably permanent ban on laptop computers and other electronic devices in the cabin. I give major credit to the EU for standing up and (rightly) insisting that burning LiIon batteries in the cargo hold were a bigger threat than modified laptops which should be able to be detected with x-ray screening. People would have died within months if these things had been forced into the cargo hold. The only other option was a cabin and cargo ban, which would have essentially prohibited air transport of electronic devices that are part of our daily lives. That is absurd. I think even the idiots running DHS/TSA realized that such a thing might finally turn the public against them enough to threaten the continued existence/growth of their bureaucracy .

Maybe in 2006 there should have been a liquid ban for a few weeks, or even a few months, while they rooted out fellow travelers of the plotters. But 12 years and counting is absurd.
