Who cares if they were interracial? They were Americans! Their killers need to be executed within the next 30 days if they have proof positive on them.
The four black murderers who killed this white man and raped and murdered his black wife apparently cared a great deal.
When a service member is killed by a fellow service member then that death should follow a shaming process that strips that person of all military honors.
When a family member of a service member is killed by a fellow service member - see above - with the service member having first dibs.
BUT... When a service member is killed BY HIS OWN MEN who then kill his family...The death should be slow and follow guidelines that are ancient and brutal.
I love people and I respect life but some times people lose their right and their brutal death becomes an example.
May GOD forgive you, I don't.
