I think the ranger might be in more trouble than Simcox. It would be interesting to see Park Sevice guidelines for drawing a weapon on someone. Was he carrying his gun openly or concealed? That would be a factor, because if he was carrying it concealed, how would she know he was armed?
I'm trying to get confirmation from Simcox himself, but apparently the female agent was of hispanic descent and she stated to the hikers that she "doesn't agree with what [they're] doing."
If that turns out to be the case, I figured as much. Thanks for the update.
