Is that a restaurant or a Wild West tavern?

Gunfight was undoubtedly a continuation of an ongoing local battle, where over-confident investigators have played out their hand and betrayed their own foolhardiness.

Suspect in shooting at Idaho fast-food restaurant died from self-inflicted gunshot wound, police say
The suspect in a fatal shooting at a fast-food restaurant in Idaho died of a self-inflicted gunshot wound, police said.
Investigators are confident that the gunman, identified as 24-year-old Chad Williams, acted alone during the shooting Saturday in Twin Falls, Police Chief Matthew Hicks said at a news conference. ¶In all, three people died and seven others were injured at the recently opened restaurant in the southern Idaho city of about 56,000 people. Authorities said Sunday that two of the injured were treated at a hospital and released, three were listed as stable, and two were in critical condition. ¶Hicks said an off-duty state trooper and an armed citizen — whose identities weren’t immediately disclosed — both fired back and diverted the gunman away from the restaurant.

Cops lauding an “armed citizen” can't be taken at face value. That's like an offside violation at a football game, where police unions, police chiefs associations and fraternal orders of police are waging all-out war on gun-owning citizens throughout the country.

Man who returned fire at In-N-Out gunman had done firearm training after 2021 mass shooting
Police credited Jordan Salinas with limiting number of victims in attack on restaurant in Twin Falls, Idaho

The “man who returned fire” apparently had a gun and he did fire it, but he’s not considered a “gunman” by the mainstream media.

“Gunman” is a not a very useful term as it applies equally to any human being carrying a firearm for any purpose lawful or unlawful regardless of age or sex or race or sexual orientation or gender identity or any other moral indignation.

And I don't care about the training or alleged training one way or the other. What did he shoot at and what did he hit when he fired? I assume when you buy a brand new firearm it comes with basic safety instructions, and if you want training, plenty of gun clubs exist to provide such training.
