I don't understand one thing. Why do the police have to follow those vans when you consider that they would be better off patrolling the streets, parks, shopping centres, fields, and so on? Especially because of mugging, attacks, and so on.
Can a police driver decided to think for himself/herself and ignore that 'Police follow this van' sign if the officer spotted something else that may be trouble? Say for example: The officer would rather check out a car and the driver that seems to keep driving around a children's playing field, than to have to follow the van just because the sign says so?
I mean, a police officer can't just actually spotted that sign, then follow that van all day??
Sometimes I wonder if the bosses of those cash van companies cut corners by buying cheap vans which could be broken into, so they would rather have the police follow the van just in case of robbery, than to have a better stronger van and well trained staff.
Why do it have to be the 'Police follow this van' sticker? Why not more effect stickers like: SmartWater technology used, Satellite tracking fitted, Live CCTV in use, Colour dyes in use, or something like that?
