In Ireland we used to have a violent police force. They often killed people. They were kind to the majority and abusive to the minority. They protected the government, not the people. It was just like France.
The people protested, for many years. They forced the government to disband the police. In 2001, a new peaceful police was created.
Not gonna lie, I feel it's getting harder and harder to organise, protest and be heard in France.
Most of the media is owned by very few people (I think it's like more than 70% is owned by less than a dozen people) nowadays so it's extremely easy to sway the public opinion. Most people are not aware of this, so the media they consume and trust are easily manipulated and so are they.
That plus the police brutality, the militarisation of the police and the blatant issues with the minister of the interior, it's definitely not going very well right now.
