Booted despite being team killed

In Reach I was flying the falcon and a teammate purposefully killed me with the spartan laser and I was booted from the game.
How does that make any sense?

Did you have any teammates riding along with you? I wonder if perhaps the game viewed their deaths as betrayals.

Yes I had 2 gunners
I was playing with some trolls which is fine I suppose but kind of irritating they can get me booted from the game.
