Why does Kim need an attorney?
Kim needs an attorney because she made a potentially false report to the police and possibly perjured herself, and would like immunity in exchange for her testimony, which she will be all too happy to embellish in order to not be hassled about her lies, all of which were geared toward staying out of the whole things as much as possible, most likely because it's the smart thing to do and also probably because her pimp doesn't want any police scrutiny.
Whew! How's that for a run-on sentence, lol!
