What he said. I used to be a U of M Police officer before I headed to the 'burbs. If you're from a nice little quiet town with little crime, you may feel like it's a "high crime" area, but if you're from a big city, it's just another area to you. Auto burglaries are off the chart - don't leave anything valuable in your car. If you want to leave your gun in your car, invest in a good car-style safe. Violent crimes, however, aren't that high. There are more cops per square mile in the U of M area than anywhere else in the county, with the possible exception of Beale Street on weekend evenings.
Don't know too many particulars about the School of Nursing or the concealed carry group.
