How would YOU catch the Ripper?

and all the above is why we don't have "way back machines".

If we can talk to people in the past, I would go and visit my great uncle Henry Cox who was a undercover cop and have a good old chat with him, also tip him off about the murders, when and where etc.
I would also find out why he believed the timing of the murders were significant.

"It's tricky this time traveling business." Especially without travel insurance.

Dig, your scenario seems to have some strange consequences. Suppose Mr A in reality A travels back in time to save the victims, but saves the victims from reality B. Suppose that Mr C from reality C travels back in time to save the victims, but saves the victims from reality A. This means that Mr A never gets to save the victims from reality B. So without setting foot in reality B, Mr C is able to change the timeline of reality B.

John, if you did that wouldn't you end up watching yourself watching the murderer?

Quite possibly. Also by preventing the murders. They wouldn't be any murders to prevent. It's tricky this time traveling business.

Time-travel.

In Dragonball Z, you can travel back in time and change things, but it has no effect on your timeline. So, you could save all the victims from that alternate reality but yours remains unchanged.

Ah yes...for some, the proof of William Goodell's pudding...

This is the kind of nightmare you can produce if you meddle with space and time :

[John Wheat]

I would watch all the murders being committed. To see who's guilty of what and then go back in time and apprehend the culprits including Jack the Ripper before the murders were committed.

I think that the butterfly effect might not only alter the subsequent murders, but us as well. But as I say, there is a contradiction here.

By coming back to today after each killing to check what has happened, if I have a time machine no hassles.

I should have stipulated that you can only make one return trip.

G'day Harry D

Never heard of the butterfly effect? Let's argue that you caught the first killer (not JTR). By the simple law of causality, the timeline has been altered irrevocably. There's every possibility that Jack will strike at a different time, different place, with a different victim, if at all! How are you going to approach that?

[Harry D]

But I'd stake out each of them, probably from Tabram to Coles.

G'day Fisherman

Then I would think that you may find yourself more than one killer, GUT...!

The best,
Fisherman

Whilst not yet persuaded by the multiple killer theory, nor have I ruled it out, that's why I want to cover all the sites and by Covering Tabram to Coles I am almost certain that more than 1 killer will be caught.

more than one

Hello Christer. Congratulate you? Yes, my friend, you are prescient.

And, by the way, you are dead centre with your observation about Annie.

Cheers.
