I had a laptop LCD destroyed by TSA when one of their lackeys idiotically pushed so many bins through the x-ray machine that it caused mine, and several others at the tail-end of the machine's conveyor, to fall right off.
I was standing a few feet away, watching, unable to point out their mistake in time. Barely got an apology, and everyone was too incompetent or unwilling to help me with any info about how to document or get evidence that they damaged it, and how to file a claim. Ended up having to 'suck it up' and accept the loss, otherwise I would have missed my flight.
Fuck the TSA, fuck bullshit security theater, and fuck people that don't understand that you can make your best effort to protect yourself and your things, but sometimes that's not enough.
