I would... disagree rather strongly that you can teach respect of authority with violence. You can teach fear of authority with violence -- easily, along with resentment of, anger toward, and so on -- but respect takes... y'know, more than that. Something whose power comes from violence isn't a thing to be respected, it's a ruddy environmental hazard. That's not something of merit, it's something to be manipulated and worked around. Fear and respect are incredibly bloody different, and insofar as I've seen they're more inimical to each other than anything else. You can see it really ruddy easy in places with a corrupt police force, if you're looking for a real world example.
You teach respect of authority through proof the authority is warranted -- demonstrated expertise, effectiveness, insight, and so on. Known risk, in the case of more negative respect like what is (or, at least, should be) shown towards dangerous but useful things such as firearms and vehicles -- and even then, that's only a facsimile of respect because of their positive capabilities. If it weren't for those, the damned things would definitely not get something you could call respect, and they'd get a hell of a lot more if that risk didn't exist. But I'd honestly say you could cook up a second word for that sort of respect and have a more accurate language left over -- they're significantly different things, and the former is the only thing I'd call genuine respect. The latter is just something we dress up useful things that can kill us with, presumably so we don't view them as negatively as we probably should.
