>> the neighborhood that i'm from, the armpit of massachusetts, it's gangbangers, drug dealers, prostitutes, and addicts. i love it. i don't know what it is about that place because it's disgusting, but i [ bleep ] love it. i was 14 when i started shooting heroin. normal 14-year-olds aren't shooting heroin. i think there's very few times i've come in here and it's not direct result of use. there's not many times that i can say i've been in my right frame of mind and walked through these doors. >> melanie reddy's prior convictions have usually been misdemeanors related to her drug use. this time she's been here for a month on a violation known locally as common night walking. >> it is prostitution. it's a form of prostitution. anyone can be charged with it walking at night in a known prostitution area. welcome to the commonwealth.
