Is it really necessary that you state that it is "black males" back there riding these apparently stolen bikes? 
Dont get me wrong I hate a thief just as much as the next man but give me a break. Cant you just say you see guys out there testing bikes with painted frames and plastics? 
If you're describing a potential suspect thats different but you're just saying you saw black guys back there riding nice quads...so they must be stolen.
