it sounds like the attacker could hardly have not recognised her, but he might still have been just trying to kill "someone famous" (a la John Lennon) and not been making a specifically political or Euro-related point.

Yes, good point. And if it was somebody like a mentally ill paranoid person and they fade back into the shadows and are never caught, who would ever be able to guess what was going on in their mind? Once your image is regularly exposed on TV, the chances of having someone deranged fixate upon you as the person that is poisoning their thoughts, food, whatever, go way up, I think.

I hope they catch him, but I just can't feel very optimistic.
