A friend of mine updated me somewhat on the goings-on in the Marvel Universe the other day, and I was rather surprised to hear that Cyclops is in prison. Yes, he also mentioned why, but neither of us were really able to come up with any really good reason as to why he should be locked up- in a ruby-quartz insulated cell, no less (you'll note that Cyclops is locked up more securely than the Green Goblin ever was...). Which led to a mutual realization- Cyclops is a child soldier.
Some of you may argue that Cyclops was above an age at which he would be considered a child when the X-men were formed, but keep in mind that he'd been living with Professor X for quite some time beforehand. Scott Summers was trained, from an early age, to fight. He led a team of similarly young individuals into combat, acting as a field leader of sorts (keeping in mind that Professor X was, often, telepathically ordering the X-men in battle), and the group was often placed in life-threatening and otherwise extremely dangerous situations. Cyclops (and, for that matter, the rest of the X-men) was discouraged from communicating with individuals outside the X-men, which is important largely due to the fact that it's an extremely necessary part of indoctrination. The group participated in regular combat training, and were taught that they were in constant danger from the outside world and could only trust the professor (and one another).
The Geneva Convention prohibits the use and training of child soldiers under Article 77.2 of the Additional Protocol I of the conventions of 12 August 1949. Those of you who recall the short-lived KONY craze from a year or so back will probably be aware of the fact that the use of child soldiers is a war crime.
In summary, Scott Summers is (was?) a child soldier, and Professor X is a war criminal.
EDIT: Apparently Cyclops is no longer in prison. Woot.
