or things aren't always what they seem.
A news item reported that a young man was seen on CCTV running out of Mothercare with a package in his hand. Staff gave chase, caught up with him, found that he had stolen a baby alarm for which he could have no earthly use. The police was called.
He was arrested. Well known to the cops as a drug user, who had been arrested for possession many times, they searched him and promptly found a package containing heroin. He was charged with theft and the usual possession. One cop, who had dealt with him before, asked why he had stolen the baby alarm when he was well supplied with stuff already.
"This shit's no bloody good, innit, it don't effing work; I been done." The young man was highly indignant. "Can't effing trust nobody no more."
He was taken into custody and his stash sent to be analysed.
The brown stuff turned out to be top grade dog biscuit, ground up.
