Can I also just say, you do seem a little angry and aggressive about it all.
You are usually calmer.
It doesn't bother me personally and my only concern is on behalf of my 86 year old parents (this sort of thing would really shake them up) and my 12 year old daughter, who frightens easily.
Don't think any of us are that bothered about people in clown masks just going 'boo'.'
I do think it was right for the CT and the Beeb to report it, as several police forces have come out and made official statements on the matter, so they obviously are taking it quite seriously themselves. In fact, I am sure the police forces released the statements before the CT decided to report on it.
As with most things, 90% will probably be harmless fun and the other 10% will make it as sinister as they possibly can.
