Either you're covering for this utter bull, or you've been misinformed,
Not only was there absolutely no Nomad activity in New York at the time, your Commander was never fired upon before he went on his rampage.
Core Hunters? Not a chance. Whether they were in his hold or not - which my scanners showed no signs of - I have clear evidence of lawful and civilian escape pods littering his hold. If you want this evidence, you'll have to contact me privately. I don't want to get any more involved in this then necessary.
A further detailed report of this experience can be found here. Read up, Commander.
