Yes. I could get a crossbow, and sleep with it under my pillow. I think they're still legal! Bloody lethal too - not to be underestimated.
A piece of trivia - You know that in America, the hand signal for telling someone to piss off is to raise the back of the hand with the middle finger extended? The equivalent British signal is to raise both middle and index finger - and this originates from the longbow men who fought in the battles of Agincourt and Cressay. If a British longbowman was captured by the French, they would amputate his middle and index fingers so that he could never again launch an arrow from a longbow. (The Geneva Convention came later) So our longbowmen, to taunt the French, would raise their two fingers to show that they still had them, and could launch arrows against the French! The gesture still exists as a taunt, or to ask someone to F.O.
