@Burning Kitty Iron Man's side is working with the government, why would they be thrown in jail for something the government organized?
Just because the government sanctions it doesn't mean every agent agrees with it, doesn't mean the agent won't lie her ass off.
OR
Just because the government sanctions it doesn't mean the Director agrees with it and didn't send a mutant who was sympathetic to his leanings.
Either way Talon was sent there to guarantee the battle didn't leave Utopia. Kidnapping a mutant under the protection of two X-Men teams (as far as I know the Jean Grey school has a team and Utopia has a team, might be wrong) will guarantee the battle will leave Utopia. Talon will accomplish the mission she will not let a playboy with a God complex ruin her record.
