Cops commit crimes everyday, they are just like any other part of society and in this case one of Seattle's finest committed murder.

Here lies the problem of Quis custodiet ipsos custodes.

http://en.wikipedia.org/wiki/Quis_custodiet_ipsos_custodes

This cop hasn't been charged with murder and justice has not yet been served. Failure to do so will just eventually lead to further violence within Seattle as public resentment will grow.

There has been plenty of information regarding the previous background of the victim and virtually none regarding this cop.

There will be plenty of folks doing there hardest to ensure that this cop isn't prosecuted if only to protect there own positions especially if this cop has been previously involved in other acts of unjustifiable violence either whilst serving in the Seattle police force or in a previous career.
