Coming into Los Angeles
Bringing in a couple of keys
But don't touch my bags if you please

For whatever reason crack allusions are a bad taste joke that people (unlike most of the above) don't seem to realise is bad taste, possibly because they consider crack addicts as either other or lesser to them, rather than unfortunate victims with a shared humanity.
I know these things happened, happen and most likely will happen and such metaphors are unpleasant for people affected, but I think it's natural language evolution.
People still get murdered occasionally and families of murder victims might be uneasy when they hear about someone that "he killed her with this joke!" but it won't prevent people from using that phrase because murders are so rare for most people that the word gradually loses its literal meaning.
