Sounds like the attack may be racially motivated.

Here's a TV news video: http://www.nigeriadailynews.com/latest-additions/36900-mang-dieke-52-mauled-by-police-dog-outside-walmart-store-video.html

How do they train police dogs to not notice the pattern that most perps needing take down are black?

What might have happened is the cop accidentally pressed the door release remote, and the dog thought "Show time! Time to take down the nearest black man. Praise and a handful of Snausages will soon follow."

Interesting observation.
