"Permissible" vs. "Should"

My progressive friend continues to send me an avalanche of "bad cop acquitted" articles.

In one of the dumps he quoted from the article

"...Gugino was violating curfew at the time, Flynn said Thursday, and “had no business approaching these police officers.” But the district attorney said he should not have been shoved. “He should have been arrested, grabbed and peacefully walked off the steps of city hall,” Flynn said. “But again, that didn’t happen.”..."

Note that the district attorney used the word "should" twice.

If you peel back the onion and keep asking the question "why", you might find out the word "should" has no legal standing.

If a police department issues regulations that claim a certain restraint hold "should not be used but is permissible under some circumstances, then the only thing the court sees is 'permissible'"

That paints the Progressive into a corner that they have a difficult time extricating themselves from.

It is an item of Progressive dogma that anybody can do anything. Any child can chose to be a brain surgeon if they choose to be, for instance.

That belief founders when it runs into jobs that sometimes require a high degree of physical strength. How can a 107 pound woman (5th%) expect to perform the job to the same standard as a 280 pound man (95th% )? (Anthropomorphic data from HERE)

Too harsh of a comparison? The 'standard issue' cop of my youth was a bigger-than-average man. So what if we go with a 75th% man at 220 pounds? 

Notice that I am not saying woman cannot be exemplary cops. Many women cops are sterling examples of law enforcement officers. But there are also women cops who totally suck at it and they cannot be fired. One local community tried and then was dinged for back-pay and had to reinstate the woman cop.

The Progressive tries to sit between two bar-stools with predictable results. "Yes, any woman can do any police job" and then they enable the less physically capable candidate by allowing (making permissible) choke-holds.

What did they think was going to happen when they told Officer 75th% Male cop to go three rounds with Billy-Badass and that he "should not" use riskier (for the perp) holds and management trains the female cops to quickly escalate to those holds?

75th% Male gets thrown back on street patrol when he returns from his injury. The woman gets an office job; perhaps as a detective or as a trauma counseling officer.

The body takes a pounding even when you "win" a fight. Why should a male cop (who on the whole are older than the women) take the beating?

Chauvin in Minnesota is going to walk. He "should not" have kneeled on George Floyd's neck because he had four officers present. But his department permitted that move.

One potential scenario is that Chauvin is acquitted. Cities burn. Biden takes the fall. Round-heel Harris steps in.
