It's pretty debatable whether the entirety of Snowden's actions can be attributed to "reasonable necessity to defend from criminal acts". He could, and did, encrypt his own comms, by which point it looks like he was pretty shielded. Dropping a lode of secret docs with journalists that seemed to have barely a grasp of security, that doesn't seem to have been the only reasonable action strictly to protect himself or even others against govt action.
