Carrying it unloaded is stupid. They won't wait to see if you have ammo before lighting you up if it came to it. Why leave yourself actually defenseless and yet a far more obvious target?
No one is going to sympathise with your obituary. "Well he looked like a deadly threat, which cops have been legally allowed to murder for decades, but he wasn't actually a threat!"
"Fucking moron" would be the common reaction.
While ICE agents are pathetic cowards, pathetic cowards have murdered many, many people throughout history. Especially ones that look like a valid threat.
