I think the girl deserves help and pity rather than hate and abuse, though I fully acknowledge that it must be horrible for Isaacs's family. Unfortunately, what can you do?
I wouldn't be able to do it myself- I freak out around celebs, as my poor boyfriend discovered after I fled a restaurant in a rather undignified way (we'd already paid the bill, so it was all right, however...). I mean, I turned around and the Weasley twins (James +Oliver Phelps) were sat there.
Hmmm... Didn't help that I left my brolly under my chair and had to send him back for it! LOL
