I just don't hate cops.
But I do know that 99.999% of being a cop is boring, difficult and they put up with idiots and crazy people - and often 'actual mentally ill people' all day, every day, in often complex situations, and they almost overwhelmingly do a good job.
If you 'have a concern about free speech' - you should be far more concerned about the vast number of people who are 'banned form campus' for having relatively normal views, but which are inconsistent with those of the 'safe zone' generation of totalitarians.
The 'totalitarianism' is not in some random guy getting ejected - maybe on wrongful terms - out of a discussion for making frankly offensive statements - but the limits on who can speak and why, largely driven by zealot students and faculty on campus, who usually represent a tiny minority of students and yet get their way anyhow.
When there is agitation and confrontation - a cops natural response is to 'can it' - and I don't mind this at all - though I would hope that if there is no crime committed that no charges are validated. A judge will eventually look at this, and if there's no validity to the charges, then they will likely be tossed.
