You can get away with a lot if you're both white and an Ivy Leaguer. Amy Bishop, the killer professor at the University of Alabama at Huntsville is an excellent example of this phenomenon.
Twenty-four years ago, Bishop shot and killed her brother and somehow managed not to be charged with a crime. I'm guessing that mom and dad are wealthy and or well connected. Stay tuned. It also turns out that the then District Attorney was William Delahunt, now a member of congress. Delahunt now says he remembers nothing about the case. Selective amnesia can be very useful.
Some years back two white men committed armed robberies in New York and shot people in the process. They were dubbed the "gentlemen bandits." Bishop kills three and is described as "Harvard educated." Being white never hurt anybody.
I'm sure there is a lot more to this sordid tale.
