You'll have a hard time convincing anyone that this "power" justified Fajo's death. First of all, Data first insisted that Fajo turn himself over to the authorities. Hardly the act of someone who thinks that an execution is the only possible option. Secondly, Data had the means of incapacitating Fajo. He had lots of options. Force him into the escape pod that was sitting right there. Disable the escape pod's computer and seal it shut. Then Data can easily force the crew to take him somewhere. Given Data's skill with computers, he would be able to overcome any lock outs Fajo had. Even if he couldn't, Fajo couldn't have EVERYTHING locked out. What's he going to do? Input his security code every time one of his crew wants to make a course change, or open a channel to a nearby vessel? By the way, if Riker can figure out how to send a secret message from a Ferengi ship, Data can figure out a way to send a message from Fajo's ship. And Data was limited limited to execution or surrender. He could stay at a stalemate. it;s not like Data needs to sleep or eat or go to the toilet or anything. he can stay there with Fajo at gunpoint until Fajo finally cracks. I assume you meant decalred war on Data. Do you really think Starfleet doesn't train its officers on how to escape captivity?
