In the Harry Potter books time travel, Time Turners being the only known method, is strictly regulated. There's a case of someone erasing themselves through careless use of it. Harry and Hermione are lucky their trip was a stable time loop (where they were or linked to the cause of events they'd witnessed the first time around), and Hermione had not only to cite her flawless academic record but also had to be vouched for by McGonagall in order to get one so that she could attend more classes than she could have otherwise gone to. Naturally one of the main conditions was to never tell anyone, and by the end of the book she returned it to the Ministry because of the stress of taking so many classes (also conveniently removing a potentially handy way to make later books easier). It's telling the Time Turners were stored in the Department of Mysteries, suggesting there was a lot that wasn't known about them (justifying the extreme measures around who could use them). The battle at the end of Order of the Phoenix trapped the whole Ministry stock in an endless loop of breaking and bring restored, breaking and being restored.

I can imagine from Day 1 there’d be thousands of cases as demonstrated in this often top 5-poll best time travel films ‘Time Crimes’ of incidences going very, very, very wrong and in the process creating chaos, no matter how much training one would undergo. m.youtube.com/watch?t=462s&v=j3eyuL0Bl9sFantastic film, one of my favourite time travel movies.

To me this is "same schtuff, different day" - how many times have various people claimed this sort of thing? I love Dr. Who, don't get me wrong. But I also agree with Larry Niven's view that Time Travel is FANTASY, not sci-fi. You can surround it with the trappings and rules of "hard sci-fi" but in the end, it really isn't. And I really don't think it's actually possible. That doesn't stop me from enjoying seeing a certain blue box spinning it's way through the cosmos... I do think this guy is another crackpot. Maybe one day time travel will become a reality. It really depends on how you view time I guess. But maybe that is more of my love of time travel fiction wanting it to become a reality. I think it will definitely be a reality one day, but it will require very careful precision so as not to change anything. You won't be allowed to time travel drunk, and breathaliser tests will definitely have to be used by time police.

Not allowed to time travel drunk lol That is the least of the problems involved! It would be impossible to police time travel for the general public. Imposssible.

They could just put a tracker in each time machine.

Don't think we'll have to worry about time travel at all really. The closest currently to a theoretical basis of time travel is theories about the effect of gravity on passage of time, so the idea that in a decade time travel will not only exist but be common seems slightly ridiculous. Unless the government want us to think that... youtu.be/m7yjRxZIUvQ

They could just put a tracker in each time machine. Even then how would paradox policing occur? We'd need to construct something that sits outside of time to record how history should happen and a system that alerts when things are going off track. Basically we'd need a Celestial Intervention Agency.

Basically we'd need a Celestial Intervention Agency. Exactly. We would not be able to regulate or keep track of the changes so if someone did change the past we would not know about it because our present would have changed.

Well, it could be true - the government are adept at secrets - the Tories have kept their Brexit plans so secretive it's almost like they don't exist.
"Taylor then said that the group told him they were not human, but actually a combination of both humans and robots who live forever." - OK....that's literally just the plot of the new Blade Runner.

Maybe there could even be a built-in camera to record the pilot's behaviour?

So those observing the tracker would have changed & would therefore not know what the time traveller in question had done in the past.

A camera would give them a reason to time travel back in time and stop the time traveller before he changes things.

Once the traveller in the past has changed something the present will changea as will those observing the traveller. If the present is changed how would they know it had been changed? & therefore how would they know to go back into the past & prevent the traveller changing things?

That presumes all actions of a time traveller are preplanned. But what about random events? Accidently knocking someone over for example or even, as in A Sound of Thunder, stepping on a butterfly. The repurcussions of even the slightlest change are unknowable.

I think it will definitely be a reality one day If so, it already is and always has been. So it isn't and never will be. Until it is, in which case I am and always have been wrong about that...

That will be like accidentally running someone over in a car: an unfortunate accident, not intentional, only slight consequences.

There has been plenty of incidents where people have spotted random figures in history with mobile phones.

We do knot know what the repurcussions would be of interferring in any event big or small in the past either accidentally or on purpose!
