The guy who has just one is more likely to be planning something.

For once, we are in total agreement.

It's not about the amount of metal, it's about what's in the mind.

That being said - When someone is spouting violent stuff in real life and/or on the Internet then all of the sudden stops spouting off. . .that's when it's time to pay real close attention.

And the guys with more than one will probably plan something
