No doubt.
I was making the point that the restraint techniques that I saw in action yesterday seemed to me to be consistent with the techniques that I am familiar with (as an observer) from my knowledge of the training that used to be given to social services staff. To describe yesterday's events as an assault is not accurate.
Did the steward intentionally or recklessly apply force? Yes. Was the force reasonable? Subjective, but running 20 yards to restrain an individual who was walking off peacefully accompanied by two other stewards with police no more than 20 meters away does not strike me as reasonable.
