Sadly, not being qualified (by rational standards) doesn't mean one can't find someone to pay them to do a job, even if in limited circumstances. I think it's worth highlighting that it still goes on, even in the world of forensics where so much public interest has been placed on the field, though it doesn't appear to be "common."
Sure, the technical aspects of an uncomplicated autopsy can be learned reasonably quickly, but the interpretive component -- the purpose and meaning of the autopsy, without which there is really no point in doing it -- goes well beyond pulling out organs and gawking at big holes or ASCVD.
Before I forget, the Federation of State Medical Boards (
http://www.fsmb.org/usmle_eliinitial.html ) lists some minimum requirements for state medical licenses broken down by state. Most seem to only require 1 year of postgraduate training, longer for an IMG, plus of course USMLE within some variable timeframe. If you believe the botox/medical aesthetic training websites then as long as there is a physician prescribing the botox (with a state license that should be doable) then it sounds like it doesn't take much to be allowed to do the procedures though that may be dependent on state law -- I've seen marketing mentions for PA's, nurses, and even dentists, for "intensive" one day injection courses. Just sayin'.
