One of many here Fatal Wyoming bear attack: No round in the chamber on handgun - Guns.com.

There is no excuse for carrying that manner under any conditions, with the possible exception of carrying a cheap substandard firearm because that is all that one can afford. Other than that, this will only happen with people whose training (if they have any) is unacceptable. There are other examples of complacency and bad training here. (He took it off? WTH?) Note that among the entities investigating this were Wyoming's OSHA. If there is a decent regulatory structure there, the company will be hammered brutally for allowing such conduct. It will also likely have real liability to the survivors of the decedent.

If you are someone who carries in that manner, or advocates for it, lose your clownshoes, improve your mindset, and get some real training, or get away from firearms. If you are an employer who has armed employees going into harm's way, and are not mandating valid training and sound conduct with serious consequences for violations, it's time to reconsider that stupidity and change your practices.
