Them not believing Bruce's character makes no sense

First of all, Bruce's character was always telling the truth. I don't think he lied to anyone, except when fake-crying and fake-begging for mercy at one point. Surely these 'professionals' would know that, adding to the fact that he's trusted enough to be sent for missions. How could they not believe him when he says they sent him to the wrong year?

Secondly, how can they NOT know he was in a mental hospital OR that he was in 1990 instead of 1996? THEY PULLED HIM BACK!

How can they pull him back if they don't know 'when' he is? I mean, if you start randomly groping at all kinds of years and months, you'll never find where he is, unless you're luckier than the luckiest luckster in a hollyweird script.

I guess there COULD have been some kind of 'automatic pullback switch' that just reaches where and when he was, and pulls him back, but the thing with that is, SOMETHING had to know EXACTLY when AND where he was, to be able to pull him back without him having any tech of his own to connect to.

He didn't have any kind of marker, pointer or drone, he didn't have a signal-transmitting device that something from the future could lock on to. Or did he? Oh yeah, his teeth, right?

But surely they would be able to know exactly where those teeth are, for them to be able to send.. was it José? to his exact location and time.

I mean, the scene at the airport PROVES they know _EXACTLY_ when and where he is, or HOW THE HECK can they send someone back so accurately, almost right to where he is?

There has to be SOME kind of mechanism, system or information package that KNOWS exactly where and when someone is, or how the heck else can they pull anyone back or send anyone to that exact time and location?

It's like going to pick up someone without knowing their location, and somehow managing to do it anyway. It makes NO SENSE!

So either the 'scientists' are crazy, incompetent or lying (or all those things), or this whole thing about 'we don't know where you were or when you were, but we still were able to pull you back when you were in harnesses in a room with locked door' is just complete nonsensical BS.

This is not even the usual 'time travel nonsense' that becomes a convoluted mess because writers don't know how to handle time travel as a concept properly - this is actually one of the RARE movies that do the time travel-aspect almost perfectly and flawlessly, as an example that it CAN be done, and how to do it.

However, why the heck would the scientists be so blind and ignorant to where and when they sent someone? Wouldn't they have ways to confirm where someone is? HOW do they define the 'time and location' they send someone, if they can't even confirm where they actually went? How can they trust a system that's non-falsifiable like that?

I can buy that the system is not very good, and that they usually send people into wrong times and places a few times before they get it right, but I wish this would've been explained a bit, because I just don't buy that the scientists could be 100% ignorant as to where someone was, when they can just PULL THEM BACK PERFECTLY.

It's like 'tracing of phone calls'-trope in TV shows and movies. Why would the phone company NOT know where it sends its signals, when IT IS THE ONE CONNECTING THOSE TWO LOCATIONS?

I mean, for a phone call to get through, something has to connect the signal from one location to another. That something, THUS, knows where the signal originates from and where it goes. Someone that manufactures a line from A to B on a map knows where the locations of B and A are.

That whole thing makes no sense.

However, the time travel-aspect is done brilliantly in this movie, kudos for that.
