Must be a chemistry major ….
Actually, when I was in undergrad, there was a Chem PhD. student at UWaterloo, who was busted for running a little side-business cooking meth in a rented unit in a strip mall a few blocks off campus. He ended up beating the charges because the Kitchener-Waterloo Police had destroyed all his chemicals, and his lawyer was able to point out to the judge that as a trained chemist, his client could quite easily demonstrate that the amount of chemicals he’d had on hand, and the amount of meth he could have theoretically produced was far less than the ‘cop-math’ figures that the court had been provided with by the police, and hence his client could not properly defend himself, as the evidence had been destroyed. The judge agreed and threw the case out. :P
