"As reported by Eurogamer, 48-year-old Anthony Bray, of Nuneaton in Warwickshire, England, was spotted carrying a replica of the iconic weapon from Nintendo’s The Legend of Zelda series openly in the local town centre.
Warwickshire Police spotted Bray on June 8 via CCTV walking down the street with something in his hand. Bray was said to have approached officers with the item visible in his hand, at which point he was arrested as he was carrying a bladed article."
He was arrested for being obtuse.
He was imprisoned for being a potentially dangerous moron. If he had the thing in a bag he would not be imprisoned for it, if it were found after a truly random search.
If we imprisoned every potentially dangerous moron, everyone would be in prison.
