Towards the beginning of X-Men: First Class, Charles and Erik visit a prison to recruit Alex Summers (later taking the moniker of Havok), but I don't recall any explanation offered as to why he's located there.
Chief Warden: What the hell does the government want with a guy like Alex Summers? I hope you're not planning on putting him with others. First guy I've ever met who actually prefers solitary confinement.
I assume he prefers the SHU to prevent accidentally harming anyone since he's shown to have difficulty controlling his energy blasts. But as far as I know, prisons aren't run like hotels and don't offer cells for rent, so he must have broken the law to get there. What crime did he commit? Is there any explanation (in or out of universe) for his incarceration?
