"after he leaves office he could then be tried for murder under US law. If the crime or intention to commit the crime occurs on federal property, it's then up to the FBI to investigate because it falls under federal jurisdiction. And they'd be investigating an ordinary citizen and not one protected by his 'office'." - Quite right Peace, they would, then too would evidence, and rules of evidence apply. My bet is that they wouldn't come up with anything and whoever set them on the case would be charged with wasting their time.

The US is not going to go back to conscripted armed forces. Defence of the realm is expensive enough as it is, you don't spend that amount of money, or even, more on a bunch of part-timers who do not want to be there in the first place. "A volunteer is worth ten pressed men" no truer word ever spoken. Take a good look at the men and women serving in your armed forces, they are all volunteers, they are "winning" in both Iraq and in Afghanistan. Compare them to the conscript shambles of a military force that was sent to perform the same task in Vietnam - Night and Day; Chalk and Cheese are the comparisons brought to mind.
