However, we can't afford to let the government's position dictate the particulars of all the facts here.
The theory that the fireworks were lit to "bring out first responders" is just that - a theory, from the government's lawyers.
The undisputed facts are that these people were working to disrupt an ICE facility, which is to say a facility of a lawless, criminal organization which, given its placement entirely outside any constitutional limitations, renders it, at least at a moral/ethical layer, ineligible for any sort of civic protections of its property or activities. A third party, who was employed by a police department, then aimed a firearm at these people, and one of them fired, in apparent self-defense at this person who was training a firearm on them. Again, I hate that they shot this dude who was just going his job. But it's certainly not tantamount to attempting a premeditated mruder.
All of this 'moving zines' business is downstream of this basic fact pattern. I'm not willing to buy the government's advocacy that this was a crime to society in the first place, so I certainly don't have any ruffled feathers about moving zines.
When the state brings its lawless armed kidnappers to heel and follows its own rules with the unrelenting strictness befitting a nation of laws and not of men, then we can talk about whether those same laws can be applied to persons attempting to disrupt its activities.
