That's a funny quote, doesn't actually break that number down by the category of offender. Reminds me of the cops in Toronto seizing "weapons" for the G20, only to later admit only one or two out of 20-something were actually illegal to own (they seized some LARPers gear too, tsk).
Would be interesting to find out what the legal view of her action or someone alerting people to police is, I would suspect it wouldn't be breaking any law - I find her's to be fairly general - or if it does, seems like a dog pile charge.
