I wonder how Americans would respond if the circumstances in this incident were replicated in the USA?

An Afghan service man, a a trusted veteran on a training course, walks out of a military base, commits murders and then walks back inside the base to surrender. Incidentally I'm sure the laws in place would mean court proceedings in the USA. Now imagine if the Afghan-USA visiting forces agreement means the suspect is flown back to Kabul for any prosecution.

Someone here may know of incidents involving off-base serious criminality by US personnel who appeared before a local court. My memory only has the low-flying training flight in the Italian Alps where cable way wires were cut and a gondola fell, killing those aboard. The US pilots did not face Italian justice.
