I agree for the most part.
I have done a bit of border area hiking now, almost always solo - and yes I carry, but I have never felt anymore unsafe than in other parts of the state. Which is to say not at all unsafe.
Pretty regularly I will be speaking with a visitor/camper at my park and they ask about border safety and express concerns from what they have heard back home in Minnesota or Ohio or wherever ... I tell them my experiences and that in my opinion the danger is way overstated.
