They don't care how much unnecessary violence they use because they know that any complaints will only go their own IOPC - Called the Independent Office for Police Complaints - run and manned by their own dirty, corrupt coppers. UK is a joke when it comes to law and order and the scumbag police KNOW that NOTHING can happen to them. At most they will get suspended on FULL PAY and then quietly moved onto a higher position when the MSM stop focussing on them.
