People like ZP and others in this thread complaining about use of force in this scenario might find that their complaints have entirely the opposite effect of the one intended.
The standard to which police use of force is assessed in misconduct cases has recently been changed to the higher criminal standard: i.e. it is more difficult to prove unlawful use of force.
This is a direct result of the problem I set out above - police are more reticient to use their powers because fear of misconduct proceedings.
As is set out in the link below:
The move has been recommended by an independent review carried out by Sir Adrian Fulford PC and Tim Godwin OBE QPM and published by the Home Office. The reviewers found that police officers do not have the confidence to use their powers of force effectively, due to past legal cases complicating their decision-making.
