The T&C government apparently doesn't think so. BUT, based on ALL of the news surrounding this "ridiculous" punishment, if you own a weapon, why would you NOT double and triple check your bags to make sure you don't make a mistake?
Going back to leaving a pen in your pocket when you do the wash. Let's say, instead of just leaving ink all over the drum, if you wash a pen in the laundry, not only does it destroy the washing machine, but also is guaranteed to jam the intake open, flooding the room and destroying everything in it. Wouldn't you ABSOLUTELY make sure you don't accidently leave a pen in a pocket? Presumably you would check before putting your clothes in the hamper, and someone would check before putting the clothes in the washer.
