Why no footage of the 'trouble' yesterday?

I've seen many vines, photos, videos, periscopes etc etc, from before and even during the game, via various sites. Why no footage of these alleged assaults by coppers, or alleged assaults on coppers?

 

Plenty of people videoing it where I was so I'm sure a few will come out throughout the week

 

Derbyshire police were using their body worn video cameras for the first time at a fixture yesterday.

Any idiots throwing punches at police can probably expect to see their faces on the next 'wanted' media appeal.
