I wouldn't bother protesting, that's not going to do anything, in fact it's exactly what the powers that be want. They are trying to provoke a conflict because warfare and beat downs is what they are best at doing.
I and many others have been writing about this for at least the last ten years.
Wake up and smell the stench of the billionaire rulers Orwellian World.
The President of the AFL/CIO noted in the film documentary; "Who Stole the American Dream," that rich people don't need the police. Rich people need storm troopers to keep the slaves in line. Average ordinary people need the police, they don't need thugs in riot gear, which is what we all now have in Europe, the UK, the US, it's everywhere.
Protesting won't do anything. You have to take your complaint to the people whom are pulling the strings on the puppets, and then you need to make the puppets cut the strings which control them.
The legal system is totally corrupted, I mean it's corrupted everywhere, in the US, in the UK, everywhere. You cannot expect justice from a criminal justice system that is itself now criminal. This arrest proves that point totally. It's time to realize that disarming the people of the UK was done for the express purposes of re~creating a new royalty class. It's time to focus the outrage where the source of the problem begins. It's time to strip the wealth from the enemies of humanity: One way or another, but the richest people on the planet are all guilty of the on~going destruction of law and order, of abuse of power, of every conceivable ill that plagues humanity. They are mentally defective and people need to understand that no human being on earth needs a billion US dollars, let alone hundreds of billions. This is complete insanity. It's uncontrolled and unrestricted power. It doesn't take a high school graduate to figure out that with unlimited resources you've got a problem going on.
