> the bombs were left in an area of the airport that require special clearance for access..
So the bomber probably has some kind of security clearance or badge?
Dry ice bombs would probably not be that dangerous. Is it possible some concerned person is trying to point out the weaknesses in TSA security?
If memory serves there was a very popular youtube video showing "how secure" areas requiring special access are/were.
The gub'ment had the video taken down and there was rumor that the video uploader was going to be charged with some bullshit terrorist law because he showed what a farce the whole airport security scam is.
