I dunno, I'm not really too worried. The SOS doesn't tell you what's wrong or who's sending it, so if you're trying to take advantage of someone that's hurt it's way more of a gamble than just listening to the comms. For one thing, fricken half the population has guns.

And as for a trap... I mean, if someone is asking for help, I'm going to help, whether it's a trap or not. You know?
