Great, now the little ones are scared.
No, no, no. Its not that bad. Nor is not "that" bad, just for clarification. I as a female, however, would not have been walking around with a suitcase at night because it may as well have been a target on my back. Baltimore is notorious for its murder rate, especially among young Black men, and an significantly large population of herion and opiate abusers. Just like many major cities. And its not for a lack of trying on behalf of the Baltimore City Health Department - you see the same thing around Hopkins even though they are buying up property around the medical campus like its going out of style to "reclaim" it. Maryland is no different.
If you're not comfortable in an urban environment then its not the place for you, but if you thought it was fine and liked the location, great! For some people it takes getting used to. In the immediate area around the medical school, head towards the Harbor and you're golden. Try to avoid the opposite direction (chances are you'd never go anyway) but even if you do, you're not going to get assaulted/mugged/whatever. Its just not as pretty as everyone wants it to be.
PS - I thought you are looking at UTSW anyway?
