Many members of our medical team are working to save someone who could, rightfully, be considered a threat. And it brought up a good point. (Yes, Tony, I did say you had a good point).
This force that brings us here isn't just bringing "the good guys". The heroes. Many of us have a past we have to reconcile with ourselves daily. Some of us
..that past is a bit more recent. It's a current issue, one that may affect others on board this ship. Some are extremely powerful and, with the wrong frame of mind, could put the entire ship in danger.
So what's our plan? Do we play it by ear? Have a contingency plan for everyone who comes aboard? Prepare extra level security just in case? Tony mentioned how it would be wrong to immediately lock someone up on arrival for crimes committed a dimension away. I do agree it shouldn't be our first action, but I don't know that it's safe to ignore those actions, either.
