Look, we're not allowed to call them "scum" - misunderstood youngsters who are bored, hence it's "our" collective fault when things such as this happen.
No, please realise that in today's Britain victims do not have rights, let alone exist. Our focus must be constantly trained on these unfortunate teens who after all are only reflecting our collective apathy by perpetrating actions as described in the above link - they are to be pitied, not prosecuted, can't you understand that?
Why these elderly people are where they are at the same time as the misunderstood youths is anyone's guess: well, I mean, if these old crumblies were elsewhere, none of it would have happened, would it? Let's get our facts straight.
So, instead of trying to blame the young, jobless, ill educated, alcohol induced, drugs raddled, foul mouthed, out of all parental control(if parents exist?), teenagers in our midst, try blaming those selfish geriatrics who deliberately attract those misguided young folk into ridding society of yet another granny or grandad.
It's not punishment they need, it's simply a pat on the head - isn't it?
