Not me, but in my senior year in high school, I had a friend who lived with his dad and step mom (who i knew were druggies but didn't do too much about it, don't ask.) Anyway, I came back from a recent cruise vacation (that my parents got me as a graduation gift) and went over to his house to hang out, when I noticed cop cars pulled up around the building.
Being wary I still walked up to the front door, which was open, and a cop looked at me. He came out and asked if I knew the family. Being honest as I could I said yes I knew them, but had no idea what was going on. The cop then asked if he could quickly search me, and I agreed. After he determined I was clean of anything, I asked what was going on. He then said they were busting the house for a meth lab. A METH LAB!!! With my friend and his 6 year old step brother in the vicinity the whole time!
Anyway, he then told me to just stand next to my car and wait. After about another half hour, he brought my friend out in handcuffs, took the cuffs off, looked at me and said "Just get your friend out of here. I don't care where you take him."
He ended up staying the night at my house that night, then the next day I took him to where his mom and step-dad lived and he lived with them for a while...though the day after I took him there I was going up again with a couple other friends to visit and got in a car accident...which was not my fault...lucky me.
