Yes, that is true.
However, I think maybe we should re-visit the definition of "police brutality"
I don't think it is police brutality to take any measures possible to bring a dangerous man who is resisting arrest under control. Many of these men are out of control, dangerous crazed man and they won't respond to reason.
I think if you resist arrest, then tough shit. If a man is allowed to resist arrest and isn't brought under control by whatever means necessary than someone else will end up paying the price as he goes on his demented way.
So, the bottom line is resist arrest and take what's coming. It's a practical approach and everyone can decide for themselves if they will be allow themselves to be arrested and come to no physical harm or resist and take your chances and if that means they take action to make sure you stay down, then that's what it means.
Too many shits are given about violent out of control men.
So, yes, I think we need to re-define what police brutality is and to my mind, it is not using any means necessary to get an out of control man, resisting arrest, on the floor and making sure he stays there. That's reasonable force-any force that keeps them on the ground and stops them being a danger to others.
Someone up thread said she was a teacher and that it didn't matter what had gone on before when referring to the airport case . She wrote that it didn't matter if a pupil had told her to fuck off many times, it would not justify her telling the pupil to fuck off once in retaliation.
This attitude is what leads thugs and criminals to correctly believe that they can act with impunity and no one in authority can say 'this far and no further.'
I believe if someone behaves badly then they wipe away their right to be treated well. Actions have consequences and if pupils started to learn this in school then we would have a better society.
You don't need to be a genius to work out that those who don't work for the good of society soon figure out that there are no consequences for them-that thy can knock as many police men to the ground as they want, tell as many teachers to fuck off as they want and no-one will dare to give them a lesson they won't forget.
A little more of a hard line, for those who have no respect for society will not make them respect authority but it will make them fear it and that is all to the good for the rest of us,
Naturally, those who wring their hands about the rights of violent men will be along to say differently and insult me, maybe even quoting some dubious sources.
