The most disturbing part of this story is the unit the men came from: 4/3 BCT. It's a relatively new Brigade Combat Team, stood up to help handle the rotation issues of the recent war, but that's a minor point. The main point is that this is a unit of regulars, part of a division that is as regular as any in the Army.
Hopefully the future reporting on this issue, and the trial itself, will reveal details that make this less damning than it initially appears. Bombing the fountain at Forsyth Park? There's no political purpose to such a thing; almost all you'd be killing is innocent children.
