Dumb story. I once stored our luggage in the garage on the same shelf as the left over fourth of July fireworks. The next time we flew was not fun.

Surely airport security scanners scan for explosive material

The explosive scanning is the thing where they pull some people out of line and run a wand over you and your gear, then put it into a machine and wait a few seconds for the analysis.

To a point, but it's spot checks at best; a state actor has full access to the wide range of explosive compounds, surely there's some that wouldn't be detected (or that can be handled and packaged in such a way that it doesn't get detected)?

Just like everything else 90s the transparent iMac G3 look is going to be coming back only in the non-ironic prison use for having everything in a clear case (to check for contraband).

This is probably the biggest impact tbh. I wonder if the US public would support these actions if it knew it was going to come back on them with longer TSA lines.
