Some questions i need answered...

[Tic]

Yesterday i was flying my Silent Night around NY, and i got attacked by two Liberty police ships, no warning or anything, regular "engage enemy" message... So as i'm trying to survive in my fighter, a Xeno passes by and saves me. To return the favour, i tracked this Xeno until he got attacked by a Liberator, later joined by a gunboat. To return the favour, i helped the Xeno, and the gunboat was destroyed.

The Liberator that was left, was armed with two shieldbusters and two rockets, so he's spamming and spamming missiles, lagging like hell etc...

So, with time, he ran out of missiles, but both me and the Xeno were still alive. He's too laggy for us to shoot down, so the fight goes on for about 15 mins with him persistantly attacking with 2 shieldbusters, unable to scratch any of us. Then, out of nowhere, a lvl 26 civilian ship shows up and brings the Liberator more ammunition. As soon as he dropped the ammo, i destroyed him. However, if i destroyed him before he gave his friend the missiles, i'd be open to rule violation report. So here are my questions:

1. Is something like this sanctionable, both from ours and theirs side?
2. Should something like this even be allowed?
3. Should people in this kind of situation, getting annoyed by enemy that can't hurt them, be allowed to fire up cruise and leave without 'losing the fight'?
