If she had done any of that I would have pulled the trigger immediately, since guns aren't as deadly by default in Mass Effect. Besides, that kind of thing takes a bit longer to do than draw a gun, giving me the time to gun her down if I had to. Hence the not a threat thing. It seems like people are trying their very best to portray her as a threat so that they can justify gunning her down while she's all by herself and hasn't even threatened you directly.
Besides, what if she had been the only way to get the ship name? You'd never know if you gunned her down. Enemies that can be taken alive are generally more useful than dead ones. But like I said, most of this is all perspective, I just find the argument "because she's a threat" to be bogus. If you kill her because of her Eclipse uniform, then I can understand that, but I stand by my argument.
Have you played LotSB yet? Liara shows how effective surprise biotics can be. All Elnora has to do is grab one of those explosive containers behind you, pull it then "bam". She
does threaten you directly. She points a gun at you.
Anyone who doesnt take that as a serious threat doesnt deserve to be a commander. Your entire point is that there is no way that she could harm you. That simply isnt true.
Generally, the moment you stop treating every gun in your face as a serious threat is the moment you die.
Besides which, i
do try to take her alive. In the middle of negotiating her surrender she reaches for a gun. Am i supposed to let her? Of course not.
