Well, Joe, clearly you have given this a lot more thought than the writers and producers did.
I gave it about 30 seconds of thought while I was waiting for some red pepper soup (very easy to make and soooo tasty) to cool enough for me to eat me.
I think even if the Enterprise hadn't been involved it would have gone down like this.
Captain Plothole: Please prepare to be boarded, you will not be able to continue until we have inspected your ship.
Ensign Made-up: Sir, they are making a run for Vulcan.
Captain Plothole: Fire at will.
Ensign Made-up: Ships destroyed. Wow, they must have been crazy if they thought they could get away with that.
