Let’s say it wasn’t a joke, who would name their explosive device bomb?

> Awful joke. There have to be at least some consequences for the kid, like getting banned for flying United for 10 years.

Take a step back. You yourself describe it as a joke. Are you really saying that the quality of the joke ("awful") should result in the origin of the joke (a kid, even!) should be banned from a major air carrier for 10 years? Does this really seem like a proportional response?

And this doesn't even begin to consider another possibility: the device was named what it was named in a completely different setting, and the owner just forgot about it. That makes it not even a joke, just forgetfulness.

Was any of this a good idea? No, probably not, but people need to calm down.
