The issue is medical schools being located in crime ridden neighborhoods v being located in crime ridden cities.
Honestly, there is really no issue at all. The thread is a fascinating survey of some of the least desirable areas of the country, but the bottom line is that around 82% of us won't have to worry about this, because we will have either zero or one choice regarding where we will be going to school next year.
The rest of us, when given a choice between a WashU, U Chicago, JHU, etc., and a lower ranked alternative located in a less intimidating place, will either figure out a way to stay safe while receiving a T10 med school education, or will trade prestige, opportunity, money, or whatever else is associated with a top tier med school for perceived safety.
As sharp as we all are, we are not going to solve the urban crime problem by next summer, and the schools will not be relocating in the next generation. My bet is very few will be turning down top tier schools in NY, Chicago, St. Louis, Baltimore, Philadelphia, etc. for lower tier schools in lovely places with less reported crime in Florida, California, Iowa, Nebraska, Maine, etc.
So, at the end of the day, what is the point of the thread, other than scaring the crap out of some very fortunate people who worked their butts off to be accepted at some of the best medical schools in the world? How many med students have died as a result of being victims of violent crime at any of these schools in the last 100 or so years? Bad things happen everywhere. You use some common sense and the odds are you'll be fine wherever you happen to live or work.
