I just found this and It's a really interesting read from some law professor who is analyzing, line by line, verse 2 of Jay Z's song 99 problems. Good education on lawful searches and unlawful searches. http://www.slu.edu/Documents/law/Law%20Journal/Archives/LJ56-2_Mason_Article.pdf
That's an interesting article, I enjoyed it. I've never listened to Jay Z before but I might check that song out.
