Check out this article in the Miami New Times: Miami Police Department Thinks Jay-Z Looks Like a Gangbanger. 

It seems the MPD did not provide an explanation for this gaffe to the New Times but when NBC Nightly News reported it, they were told that the images were just a "place-keeper for artwork they were developing" that were "mistakenly" posted online.  

Really? A place-keeper for artwork makes using it okay? Give me a break. That’s so wrong on so many levels. Of course, since it was brought to the attention of the appropriate folks at Miami PD, the image has been removed but it should not have been used in the first place. I’m just saying.
