Regarding the previous legislation which led to the wrongful arrest of protestors, a number of human rights organisations issued warnings about it before it was passed.

For example:

> UN High Commissioner for Human Rights, Volker Türk, called the Public Order Bill “deeply troubling legislation”, after it completed its passage through parliament on Wednesday.

In fact, the UK category of the UN news feed makes for pretty embarassing reading in general, speaking as a Brit:

Mainstream news sources (at least the ones I follow, I'll admit a left-leaning bias there) were all shouting about how this was the inevitable conclusion of the legislation, to be countered by ministers appearing to say that no, of course it wouldn't be abused.

> followed by 'nuthin burger' from the same sources? That's what seems to happen in Canada at least.

Didn't the government just suspend the constitution (that's a thing over there?) because of some peaceful, free-speech protected, protests in the capital and start arbitrary freezing protester's bank accounts?
