Yes, I'm aware of all that. I was aware of it when I first thought this up 28 years ago, and I was aware of it every time I've rewatched the episode since. That's exactly why I specified that it would need to be a grazing shot aimed away from Fajo's body.
As I've already said, the whole reason this is a problem is because the device is a box he's wearing
on his side, sticking out from his body. So your "brain tumor" analogy misses the entire point. Since it's sticking out from his side rather than centrally located, that means there are firing angles that would graze the device yet miss Fajo's body altogether. As for what we know about the Varon-T disruptor, we know that
it fires a fairly narrow beam, so such a grazing shot is possible. And Data is precise enough to make such a shot.
"Beam" is rather unspecific isn't it? We have no idea what that beam
does, like whether it's capable of "Grazing" at all. All we see it do is rip through Varia entirely, which IMHO, based on the flavor of its description, might be the only thing it's capable of doing, ripping through everything & every adjoining thing it's fired at.
It has to fire through Fajo's forcefield. We've no idea what effect
that will have, such as dispersion, & we've no idea what kind of beam it fires, or what firing it at something adjoined to Fajo, via his belt, will do, like possibly total annihilation ala Varia, because its effect spreads, & it's attached to him
I'm sorry if my analogy fell short for you, but removing a tumor from the
side of a brain is just as impossible with a battle axe, compared to a scalpel, as it would be centrally located. You're inventing what you think it should be able to do, to claim the episode doesn't hold up. That's on you, man, because I don't concoct my own narrative to shoot down the show. If I ever do it, it's to support what we see, or offer an alternative perspective that is just as supportive
I'm not talking about the failings of a nonexistent, fictitious 24th-century android, I'm talking about the failings of the real, 20th-century TV writers and artists who created a story about him. If the field generator had been something like, say, a belt buckle, an armband, or a mesh suit covering Fajo's entire torso, then the setup would've worked as written, because there would've been no firing angle on the device that didn't also hit Fajo. Similarly, if the animators had made the disruptor's beam much wider, or had it spray around unpredictably like a Ghostbuster's proton beam, then that also could've ruled out my alternative, because then there would've been no chance of Data aiming precisely enough to hit the box and miss Fajo. But that's not what they did. Given the way the box and the beam were depicted, Data had an option the episode's creators didn't intend him to have. And that's why I can't buy the episode's conceit that he was out of options.
You're just describing what you think they should do in order to fully satisfy your own personal interests. I'm sorry, but no writer can do that for every individual viewer. If you want to believe Data could make this hypothetical shot you describe, you can invent an indeterminate number of ways, that would be wholly unrealistic for a writer to predict or address, let alone that scene's production staff, costume designers, prop department etc...
Heck, I could suggest Data actually didn't fire at all, as he never pulled a trigger or switch. He only leaned in a bit. So it's possible he's being wholly truthful, & that some inadvertent thing occurred during transport that caused the weapon to misfire in the matter stream. I
could say that, but don't, because it shoots down what the episode is presenting, & doing so would just be a nit pick at the prop department for not having a noticeable triggering mechanism on it
No offense, but your example is exactly the same imho
Edit: OOO! I just thought of another just as plausible, made up narrative... Follow me here. Data DID shoot at Fajo's field emitter. Sure, it may
look like Data is aiming for a kill shot, but he could know exactly how a Veron T Disruptor will make contact with Fajo's forcefield. So he knew exactly what precise angle to aim the disruptor, in order for its beam to get redirected after hitting the field, such that it will "Graze" the field emitter, & lower the forcefield, allowing Data to apprehend Fajo. There, problem solved... even though that's not what happened
