Has there been anyone (caught, documented, etc.) who likes to steal ... security alarm systems? Whether from areas guarding these police boxes mentioned in the post, or from other locales?

To me, trying to steal something that by definition is aimed at preventing theft -- there's some sort of meta-irony, yet brilliant idea. in that. If it was done the right way -- and if that was the sole fetish, the theft of the security apparatuses themselves.
