This situation is so different and so much more appalling than anything in recent history that there will definitely be an independent public enquiry, and all sorts of views on the impact of counter protests should and will be considered. I don’t think that standard lines to take will cut it at all.
Serious answer, you're treating the police like a hive mind. I know one former officer who would support counter protest if they dont make themselves a problem, Im sure there are many who think that way, and many who don't.
You'll find a variety of opinons because people are people. So its not a question anyone here can answer, even if they are an officer. They'd speak for themselves.
