I know this story well. I learned of it soon after hearing about the verdict from the suit filed by the King family. Since, I've seen all the reports and interviews as well as the one's you have done. An exceptional job, I might add.
It's a sad story but something every person should be aware of. The US government isn't there to protect anyone other than those interest who are certainly not considering the well being of Americans or any other nationality.
It's too late for justice in this case but it isn't too late for people to realize that government isn't the answer to our problems, it is the problem.
This story is just one in a very long list of injustices that has gone on and continues to go on each and every day. As long as tax payers continue to support it... it will continue.
