To be fair, if the deputy had reason to know that Cruz was likely to be armed and dangerous, proper police procedure most likely would have been to await backup before confronting the suspect.

Four deputies failing to stop Cruz is another matter entirely.

The EXACT opposite is the case. He was carrying a duffle and a backpack, no weapon in sight. Proper police procedure would be to challenge him as he headed to the building.

The following is not all in reply specifically to you but should be said.

To all:

That's a myth that's making the rounds, and it's been disseminated to many unsuspecting, good and even smart people as fact. The myth has also been presented many times by popular media in fiction. But that myth has the potential to motivate more mass murderers.

An officer at the scene of an active, armed attacker must stop the attacker immediately. Otherwise, the attacker will probably quickly wound and/or kill many more victims. There are many children in each of most schools, and their parents--constituents--will not tolerate a policy that allows them to be murdered for the purpose of keeping government employees safe from the psychopaths who resulted from their anti-family judicial policies (see decades of academic feminist presentations for judicial officers).

To some:

So for police show buffs and union member relatives here, how many children do you want sacrificed to medicated, murderous sons of bad social policy for the sake of absolute officer safety? How desperately do you want to have our Second Amendment to be repealed because of a policy of standing aside for mass murderers?

We family rights advocates told you all during the '90s that the superpredators were coming because of your rotten anti-family laws and policies against men. They're here.

Either make sure that your public servants stop them, or get the lifelong civilians out of the way to make way for real, combat-trained prior soldiers to do it (infantry, engineers...but not rear echelon military lifers).

The age of preferred policies of the Clintons is coming to a close. If elements of the social left are willing to abandon those evil policies, maybe we'll just call a couple of generations of failed experiment an error instead of a crime. Let's get back to the future, and do as our forebears tried to teach us to do. That's conservatism.

“if the deputy had reason to know that Cruz was likely to be armed and dangerous, proper police procedure most likely would have been to await backup before confronting the suspect.”

Cowardly cops do that. Cops who actually intend to protect and server draw their weapon and confront the dangerous suspect.
