While this is a positive outcome, it's also a lesson:

Governments will do whatever is in their in interest - whether legal or not - in the moment because there is no accountability.

The 'accountability' in the case is two years after the fact with the courts saying, 'you shouldn't have done that.'

But that's of little satisfaction to the citizens financially injured at the time by government police action. And that police action derailed the protest as designed.

Governments will always protect their monopoly with extralegal means and say 'oops' later.
