Granted, there are times you have to violate rule #1, which is why I have a permit. But was this really one of them?...go to zone full of law enforcement...and full of people provoking law enforcement? And if you do have to accept the risk of going to such a zone, maybe you also accept the risk of not carrying a firearm.
Another rule: Always comply with law enforcement. The only time to violate that rule is if you are a revolutionary. So why did he resist? Was he intending to revolt against our government?
Willing to wait for facts, but the dead dude had to make a number of decisions unrelated to ICE to end up dead.
Regarding his gun: Not really a carry gun, IMO. It is big, and it was made bigger with the site. I know some people carry big guns, but you sacrifice concealment when you go big. Then again, when it is so cold, maybe size of weapon isn't a big deal.
[Edit to explicitly state that I agree with all your points in your post above and your post below.]
