Being tolerant of minor law breaking could mean just about anything. Afaik people already can legally protest although I don't know all the ins and outs. Either way all the document reads at least to me is "let us break the law and have no accountability while the police do nothing".
No minor law breaking would be flinging bottles at the cops. Major law breaking would be flinging bombs at the cops. Or atleast that's how id interpret it. I mean fuck I've seen alot worse then bottles flung at cops before granted we always had the fuckers outnumbered or where just able to run faster then the fat cunts. But as cops will go off the head over fucking anything it shouldn't be a issue anyway. Atleast this way if the cops cross the line before the protesters do it makes them look bad which is not a bad idea actually.
