Example: Antisemitic rally being held by the national jewhaters’ league. Robert the rabbi with his skullcap shows up in his very conspicuous Jewish garb to proudly sing some Jewish songs in the centre of the protest.
Polly the policewoman pulls him out of the crowd by his arm, bringing him across the street while explaining that it’s being done for his own protection.
Polly adamantly insists that she cannot have him return because him singing those Jewish songs would potentially cause a breach of the peace, as could already be seen just before when he began to elicit anti semiotic insults and taunts from the jewhaters’ crowd.
Robert continues defiantly singing his Jewish songs before Polly then promptly arrests him for a breach of his majesty’s peace.
Did Polly correctly use or exceed her legitimate legal powers as a policewoman?
—— According to Polly he was suspected of committing a breach of the peace but in reality can singing inherently inoffensive songs alone constitute a breach of the peace? I think poly’s previous remarks suggest that in spite of her later claims her overall conduct was rather motivated by a desire to keep Robert safe. I think it’s possible that what Polly actually meant was that rather than committing a breach of the peace, Robert might has been at risk of provoking others to imminently commit a breach of the peace against him.
But if there are only reasonable grounds to think that other parties than Robert may be about to commit a breach of the peace, is it fair/lawful to arrest Robert for his own protection, instead of arresting the ill tempered others so as to prevent the breach?
