I love The Wire. It is extremely realistic- the cast consists largely of Baltimore residents who've experienced life in low-income Baltimore neighborhoods. Our real mayor has appeared in the show several times. I think that's pretty cool.
Baltimore is a crime-ridden city. It's also a ton of fun to live in. Most of the crime in Baltimore (shootings, assault, etc) is related to the rampant heroin trade here. Heroin is truly an epidemic. When I drive downtown (about 15 minutes from where I live), there is a stretch of road on the way into the city on which there are heroin dealers standing on every single corner (maybe 20 blocks?). They will literally YELL to you at red lights that they are selling heroin. It's unnerving, but they don't harass your or anything. The sad thing is, they often employ children (13-15) to carry the product because police aren't allowed to search minors without the presence of a parent/guardian, and most of these kids' parents are addicts. The police do almost nothing about it because it's so rampant. Some neighborhoods have been successful driving dealers out by calling the cops every single time they witness something shady. A strong, active police presence seems to make a difference. And expensive real estate. That also makes a difference.
There are currently more than 60,000 heroin addicts in Baltimore. One of my best friends from high school is an addict, as is his older brother. Evan threw his life away for it- he left for the University of Delaware in the fall of '05 on an engineering scholarship, and came home after a week because he got so sick, he couldn't stay. It's heart wrenching. And no one understands how strong and painful a heroin addiction is unless they've been close to it. Kids here try it one or two times and they're in the throes of a full-blown heroin addiction before they even realize it. It's unlike any other drug in that way. It hits me so close to home in so many ways that I get really emotional about it. My friend Evan is still alive (struggling with hepatitis and chronically infected injection sites, but still alive). But the life he's likely going to lead for the rest of his days makes one wonder if he wouldn't be better off dead.
There's so much cool stuff in Baltimore (Charm City Cakes, National Bohemian Brewery, the National Aquarium in Baltimore, the Shot Tower, the Inner Harbor where the national anthem was written, etc. etc.). I would say the portrayal of this city on the wire is absolutely realistic, but really one-sided. For almost every single shitty, crime-ridden neighborhood here, there's an upper-middle-class neighborhood that sees almost no crime. Yes, walking in some neighborhoods will put you in danger of being shot. Sometimes you have to drive through those neighborhoods, but you are fine if you just lock your doors and keep driving without staring (I'm only kind of kidding). A lot of people get mugged, etc, but I wouldn't say that kind of stuff is that much more common here than anywhere else.
Let's just say, it's super easy to get high here or shot here if that's what you want to do. But it's not like you CAN'T come here and NOT get high or shot. It's actually pretty easy to avoid
