Yes! There are two places where there have been issues with taxis. (Though the first link is broken, so I can't tell exactly what the issue is -- judging from the URL it involves a cab driver that raped passengers.) This proves that all regulations everywhere are a waste of time. More seriously, nobody claims that the existing regulations ensure that there will never be an issue with a taxi. The claim, of course, is that things would be worse (or, if you prefer even worse) without them.
