I would disagree to an extent, though I do quite understand your point and that risk.
I would rather have it that way than this hodgepodge dog’s breakfast of contradictory and often confusing rules that got this poor guy a jail sentence.
The fact that I cannot cross a border without fear of inadvertently transgressing some dozens of different rules and regulations and ending up in jail like this guy means that whenever I travel out of state, I am unprotected. And those times on the road are times when you may have a greater need of the right to protect yourself with a firearm (being in unfamiliar places, etc.)
Sure, I could familiarize myself with my travel route, all the places I go, get the book on all of them and learn it, but...I am only human. I may forget some key factor or rule, and as this shows, the a-holes that wrote and enforce these stupid laws don’t care if they destroy an individual, as long as their political goals are achieved.
How I despise Leftism in all of its forms.
Then don't travel to states you can't conceal carry. Problem solved.
