Not sure where the law stands on it these days, MfH. It was a well known trick, the hip flask would contain lucozade so you could knock it back with ease... particularly after a crash when you need to settle your nerves. The other one, which I think has been addressed, was to cut yourself and demand medical attention... no matter how small the cut they couldn't refuse and couldn't do anything else until that was attended to... there was some catch in patient privacy rules or something that meant the hospital couldn't cooperate with the Gardai in conducting/sharing/facilitating blood/piss tests.
