Alien 1, Alien 2 and others in “Unfinished Business”

We were merely curious, we meant no harm!

We did not, after all, injure you in any way!

Picard

Imprisonment is an injury, regardless of how you justify it. And now that you have had a taste of captivity, perhaps you will reconsider the morality of inflicting it on others. In any event, we now know of your race. And we know how to imprison you. Bear that in mind. Now get the hell off my ship.
