It's not easy to draw a police sketch. Artists -- working with hazy details and limited information -- sometimes struggle to produce exact representations.
Other times, there are no excuses.
After the 2014 murder of Rabbi Joseph Raskin, police released the above sketch of the suspect. While not every police sketch has to be a Renaissance painting, it's unclear what, exactly, the public could expect to grasp from this ("The suspect may or may not have a nose. Residents should immediately call police if they see anyone with a chin. That chin may also be a wrinkle. Just ... call us okay?")
The suspect was later identified to be 15-year-old DeAndre Charles, who was arrested on Dec. 9, then charged with first-degree murder and attempted robbery. The evidence against him has yet to be released, though prosecutor Katherine Fernandez-Rundle described the case as "evidentially poor, but factually rich."
Compare and contrast for yourself.
