with mob mentality anything can happen
That is so true. Many, many, many moons ago, I was dating a police officer (a motor bike cop). He and his partner heard a radio call for assistance at a football match where the fans were on the pitch rioting. As he and his partner were on motorbikes and not too far away, they responded knowing that they would get there quicker than the police cars. They parked their bikes and ran into the stadium; unfortunately, they ran in at the wrong end which meant they, just the two of them, were running into the approaching, rioting crowd. Needless to say, they turned and fled!
The police do need methods of control when the crowd has lost their own - and in sufficient numbers to deal with the crowd.
