Unmarked vehicle, maybe no license plates (STOLEN?), left running in the middle of the street--ABANDONED? CRIMINALS?

Nope. Highly unlikely you would be able to plausibly convince a jury that you actually thought this was an abandoned car, possibly by criminals.

You find them first--THEIR problem. You do NOT know they are anything BUT criminals. Treat as such. If they want to play tuff-boy, then kill them and let the local cops deal with the bodies.

I think you have a wildly inaccurate expectation of how that particular confrontation would go down. If you tried to get into a physical confrontation with a bunch of ICE agents, I don't think it's likely that it would be their bodies the local cops would have to deal with. Remember, these are heavily armed law enforcement folks who are trying to bring someone into custody/detention - and that they have to approached under the assumption that they might have access to a weapon.
