During the summer months when it was hot and humid, I'd sleep during the day, and friends and I would sneak out and walk all over the city in the middle of the night, we were only 11-12 years old.
Yes, we hung out on the stairs of our row houses, and on the corners of the streets, and played radios loud, but by and large, violence was confined mostly to bullying. In fact, we had often walked down Pratt street past Martin Luther King Boulevard with no problem from the people living in the projects.
Things changed after the drug war started in the 80s. I started experiencing shootings. Kids got shot at my school. I'd hear gunshots all during the night. I even got caught up in a shootout at one point, which sounded like firecrackers going off if it wasn't for the sounds of bullets ricocheting off of the brick houses (thank god old Baltimore rowhouses had real brick facades)
Many of my childhood friends became drug addicts, crack houses sprung up around my home. One of the friends I knew who I thought would graduate highschool and college, who was smart and into electronics, ended up as the neighborhood drug kingpin. Older neighbors and others who could, fled the city for the suburbs. Homes were boarded out, and soon, it looked like Mad Max. Our house sprouted bars on the windows.
If it hadn't been for my 300 baud vic-modem and Vic-20/C64, I wouldn't have gotten off the streets. I mostly survived by vanishing into the online world, and staying in libraries, and avoiding the streets.
To me, the war against crack cocaine is what leveled Baltimore. Not the drug itself, if the government had treated it as a public health problem, things might have turned out better. But the drug war only served to make drugs the most lucrative, most important part of the local economy, and for the losers in that economy, the dopamine it provided became an escape from despair.
