> I'm old enough to remember the poisoned Tylenol scandal. And I think they managed to do it DESPITE tamper resistance.
Actually no, the Tylenol incident did kickstart the tamperproof packaging on almost everything edible, not just prescription medicine. At that time you could take an over-the-counter medicine bottle off the shelf, pop the top off, put it back on, and no-one was the wiser. Not even a plastic band around the cap. Yup. People trusted lots more back then.
I did a paper on that incident in college to satisfy "do a paper on something security related" and the instructor didn't specify "computer security" so he was impressed how I did make it related.
