Stayed at the Peabody during a conference in 2008. I remember the briefing we got about Memphis. That gave use maps with perimeter markings and said as long as we stayed within the perimeter we were safe. Step outside and you were on your own. Couldn't round a corner without seeing a cop. Spent a good bit of time on Beale Street.
The morning I left, we passed a Waffle House just outside the "wire" with crime scene tape everywhere. The driver said they had been a multiple homicide the night before that included a pregnant lady and her child.
