weird halo 4 unsc violation in spartan ops

I managed to get a weird unsc violation in spartan ops at the end of episode 10 chapter 2 at the part were you free the humans. I never shot any of them at all.How does this violation appear anyway?

Because someone else on your team kills them.
It happened to me before, -Yoink- annoying if you ask me.

That sucks.At least the violation happened at the end of the mission for me.

How bizarre!

What actually happened? Are you still able to finish the mission and get the exp?

Happened about 5 times to me yesterday in one game, really annoying

> What actually happened? Are you still able to finish the mission and get the exp?

Yes!I just died because a teammate thought it would be funny to kill the people we rescued.

If you melee them, you also get that violation.

I wasn’t near them at all when that happened.
