Baltimore is worst than what you see on The Wire, and this is well known. It's also a worst city than Detroit when it comes to homicides and crime in general. What are you talking about? That still ain't gonna stop me from going to a gas station at night.
Okay, tough guy. I'm not one to argue about which city is the grimiest. I think that it's stupid. I can tell you this, though....
I'm sure that you've never been to Detroit. You'd think differently if you've actually been to the city. I've been to some of the worst hoods in North America (Mexico included). If you're doing well for yourself, you'd be a fool to go to certain gas stations (day or night) in Detroit. Pull up and see 8 hungry nikkas just standing around waiting on their prey. People lurking. Bums/crackheads asking for money etc.
But you're a tough guy, so I'm sure that you'd be fine.
