Brown family "profoundly disappointed that the killer of our child will not face the consequence of his actions."

You have that wrong--your "child" (who was an adult) faced the consequences of his OWN actions.   Evidence does not lie, people do.  

So now we are left to ponder the fact that the President of the United States sent representatives to the funeral of a man who attempted to kill a cop.

Nice addition to your already sparkling legacy, Obama.
