Most all of us have by now heard of the tragic and senseless murder of four US Marines in Chattanooga, TN. Right now the details concerning the shooter and/or his motives for acting the way he did are still under investigation. But this much we do know: Four sets of parents have lost their young sons. Maybe some were husbands and fathers. If so, more people are also grieving over this tragedy. I'm sure when these four Marines left their homes this morning, they had no idea that they'd never return to them again. IMHO, all four of them deserve to be posthumously awarded the Purple Heart medal, even though it's of small comfort to each of their families at this time. As a military vet, this just tears my heart out when I hear of things like this. They were only doing their duty, now they're dead. Please pray for their families, and for our nation for which they gave "their last full measure of devotion."
