Actually I have been mugged as it happens and in quite frightening circumstances.

And so I can understand that those involved might well have all sorts of vicious feelings towards their attackers.

I just happen to think, that as an observer, it is possible to be angry about such attacks and to empathise with victims without extending out into generalised commentary about groups of people.

My point was that if the CCTV clip had been seen devoid of the context, would those people still be seen as 'scary' or 'scum'? Neither could I possibly say what these images show about whether those people are respectable etc. or even whether they are 'obese'.

What I think about the motivation for such offences is not relevant to the points I have tried to make.
