You can't separate the two parts, the threat and the policing the disagreement.
Of course you can. The police responded to a report of someone being threatened.
I am indeed suggesting that's what they were implying. On the basis that they clearly didn't take the feeling threatened seriously
Right, so they responded to a report of someone being threatened. When they arrived and spoke to everyone they ascertained that it wasn't really a case of someone making criminal threats, it was an argument about single sex spaces that had got out of hand, and it was highly unlikely that anyone was in any real danger, or being threatened with real danger.
otherwise why didn't they ask Miranda about it AFTER having spoken to the TiM?
Who knows? Perhaps the behavior they described to the officers didn't meet the bar? Perhaps, having been removed from the conflict and calmed down, they'd realized they'd overreacted in the moment?
You don't know exactly what was said to whom. Miranda said they were told to stay away from eachother...if there's no accusation or evidence of a crime, what else needs to be said?
making a judgment call that Miranda hadn't actually posed a threat
They made that call once they'd attended and got all the facts. They're not suggesting that someone who felt threatened at the time shouldn't have called them, or that it was a malicious call.
