Newark, NJ is like that; they try to keep the consumers there after they get out of work (or draw others in who don’t work there), but they know better. After dark all bets are off; if there is a high profile event there are more police than attendees.
I worked in downtown Detroit for a few months, my first day, my boss sat me down and said “Rule #1 - You are NOT to be in this building past 4:30, make sure you are on the road by then.”
