20/20 is always a mixed bag. They strive to hit issues of consequence, but often make their stories more about them values than something that is holistically true.
I would never accuse this team of telling lies. They don't. They're seasoned professionals, they only tell the sensational story and omit anything that doesn't support it.
In this episode they minor on the criminals, major on indicting the establishment and ignore their own bias. Vanessa was a victim, her family was mislead by bias and supported by ABC. The story needs to be re-examined by someone not pandering to ethnic bias.
The world is falling apart and their big story is that the Army didn't lock down the base when someone didn't show up for work. I'm guessing ABC alerts all of their affiliates when someone in the mailroom doesn't call in.
