I got shoved in the back at Millwall for fuck all. The crowd were singing (football chants, nothing malicious) at other fans across the station on a bridge (no way of actual confrontation) and the police decided to herd us up like cattle rather than let the crowd continue naturally on to the train 100 meters away so avoiding the crowd from becoming hostile.
In general I've found policemen are bully victims with chips on their shoulders and authority junkies that crave respect, but do very little to earn it. Rather ex-military men took over as they have discipline and more common sense (not saying this would be a perfect solution, but surely no worse than the current lot).
Manchester police take incompetence to another level, cba explaining why, but feck me the Manc force is a shambles. Burns my head to even think how half of them get hired.
