Kath, feel very similar but still a tiny bit of me cant help but cling onto hope that they're wrong.
Welshcowgirl, I suffer from anxiety too, so get where you're coming from. Robbery and stuff, you hear of copycat things, but these are very simple crimes. The sort of crime we are talking about here, you have to have serious pyschological issues (IMO), a motive and so on, therefore a copycat style thing is much less likely. Especially as we are unlikely to find out exactly what happened and why until a trial (so usually over a year away), if ever. Therefore they wont even have anything to copy as they wont know what has happened.
