Isn't it obvious? British wig headed judge beating down a protester with his hammer thing. Protesters sign is blank could mean his message goes unheard, the authority is effectively silencing people.

Tell me what message you get from it.

The protesters sign is white. As if he's saying I surrender to the judge and the judge ignores it splatter in the flag with blood.

Over prosecution, abusive of power.

I really should go for a bike ride.
