Yesterday, a Grand Jury refused to indict Darren Wilson, the police officer who shot Michael Brown in Ferguson, Missouri.
This could have been predicted from past outcomes quite well. Police Officers are rarely indicted, much less convicted, of offenses related to their handling of suspects, even when, as is not infrequent, the suspect ends up dead. How many deaths are caused by police? About 3% of all homicides. Further, there is considerable evidence of racial and other biases involved regarding who ends up dead after an encounter with the police.
Here is a great article from the Nation on why it is impossible to indict a cop, what reforms don't work, and what should be done.
Here's a Daily KOS blog which evolves into a very lengthy discussion on the Ferguson Grand Jury and the prosecutor Bob McCulloch (this blog includes several pro-Wilson commenters btw).
