Sweaty jocks?

I know nothing about Katie Hopkins, other than that she clearly makes a living out of being controversial - offensive even.  The question seems to be - how far can she go without falling foul of the law?  You might think (and I do think) that Twitter should be seen for what it is - idle chit-chat - and that the law should keep out of it.  But apparently there are those who not only take offense at what she says, but are demanding that the police take action.  Can't decide who is the sadder - Ms Hopkins or those who rise to her bait?
