Obviously, it was _______

And if this one is blanked out, too, then you know I'm the newest addition to the Watchlist.

It's not blanked out for me. Clearly the NSA is interfering with your web experience.

I didn't mention it cuz I figured if they're monitoring calls for it then they're damn sure monitoring posts for it and I didn't want to end up on a list. But what the hell, I'd rather learn more about what this is really all about. And that's the thing: the word wasn't even that crazy, unless you're on line at an airport (apparently) which I wasn't.

The word was "bomb".

(...Now that I think about it, I was at a train station. Not a major one though, doubt if that's related.)

People use the word 'bomb' in conversations on the phone all the time. Nobody is getting their calls disconnected for saying that, I assure you. It was a strange coincidence - a fault on the line or similar phenomenon.

Agreed, it's an incredibly popular word, and even if calls were just being dropped in train stations, it would still be widely known. Plus, what would be the advantage of dropping the call, and allowing the person to redial? If the call is being monitored, wouldn't it make more sense to send the audio to security for review? If they're calling from a public phone, you could activate a silent alarm so they're randomly selected by security, or simply redirect security cameras to their location.
