I never saw Lee's action ooc. Or caused by his sympathy for Roslin. Not that said sympathy isn't there - these two do have a strong relationship - but if that was all, and he judged her to be wrong or the worse alternative, he'd have left her in the brig. As you say, he's on the side of the law, not of a person, and that's what Tigh just doesn't get (and neither did Adama before being shot - we'll see whether he does now).
Additional factors for his timing: Dualla told him Tigh was hitting the bottle, hard. Now Dualla has served with Tigh for a while; presumably she knows he's an alcoholic just like everyone else does. If she thinks that the quantities he consumes are extraordinary, they are. If she, who is an Adama loyalist, tells this to someone who's on parole and adds she wishes someone else where in command, it's a writing in flames on the wall that Tigh is rapidly losing what respect and obedience he had in the military, and the civilians are opposed to him already. Things were getting uglier and more explosive by the minute. Action was called for. I suspect that if Roslin had died of a heart attack in the brig right then, and Adama would not have woken up, (some of) the crew would have mutinied as soon as they'd be ordered to get into a shoot-civilians-situation again.
Sidenote, caused by talking of addictions: it's worth noting that Doc Cottle, who not only has more facts about Roslin's cancer and just how it affects her than anyone else in the in the fleet and knows about her chamalla medication, and about the effects of chamalla, still helps her escape when she asks. And he's military, not civilian. If he thought either the medication or the illness itself was affecting her judgment or making her a worse choice than Tigh in this situation, you'd think he'd speak up and give Tigh a reasonably good justification for keeping her out of office. But he doesn't.
