If things were peaceful, there would be no media coverage. The real protesters need to ride the wave of violence if they want to be heard.
Media coverage is helping absolutely no one at this moment in time.
There is absolutely no outcome that can come from this protest at this moment in time.
The court is hardly going to say "Oh wait, hang on, let's reconvene because everyone is angry outside!".
Protesting now does nothing. It won't make a difference because there is nothing to be done right now. It's too soon.
Protesting later on, when tensions are lower, say in January or February, peacefully, will bring this back into the spotlight and show the public demand.
The protest doesn't have to be violent to draw in the media. The media just happen to flock to anything violent.
They'll come to a large peaceful protest too.
