Minimal coverage that I saw of this, Worldnet Daily, Breitbart, Inquisitor picked it up. That's about all I saw. Guess it's not news.
My first reaction, other sources described this happening in the Mohave, was that it was in the reserve. Beautiful place, have camped there, and not a bad spot if you want to be isolated. To howl at the moon and such. But it's illegal to discharge a firearm there, though you can possess one. I assumed that's why the FBI was involved.
This article, a local CBS affiliate, describes it as a campground in a national forest. I suspect they're correct. Some of the California people can weigh it, most national forests I've been in it's not a good idea to be discharging firearms in campgrounds. Usually that would be a local issue, or state. Not FBI, unless there were other considerations.
Were they not chanting allau akbar and shooting, rather playing Charlie Daniels too loud in the wee hours, they'd have been cited.
I'm not going to suggest the bad potential outcomes should someone in the area misunderstand their actions. Nor if they'd been 25 miles east chanting and firing at 29 Palms.
Best case, uncivilized, dangerous behavior.
The MSM won’t cover anything like this, it wouldn’t be PC.
Just a group of pacifists yelling Allah Akbar, nothing to see really.
