There is no "staged media campaign" to smear people, the media was reporting on the fact that having kids in the red zone had become illegal with the emergency orders. Kids come to protests all the time, it is not a big deal, but when the cops hand out flyers telling you that you have to leave and you don't, keeping your kids there with you, you are going to get some extra attention - it is not remotely comparable to church, women's centres, or union picnics. If you brought your kids to walk the line with you on a wildcat strike that might be comparable.. if the cops had handed you a flyer saying they were going to forcibly remove your picket line soon.
I agree that early enforcement may have made a difference - but it is clear from the reporting that towing vehicles at the outset was never an option - the towing firm that moved a shack /at the request of the protestors/ received a huge amount of harassment. In other cities pre-emptive measures were successful - sometimes by the police and sometimes by citizens. In my most generous moments I sometimes can forgive the OPS for thinking that this wasn't that big a deal at the start.
