I most certainly do not accept that it is "impossible" for Oswald to be around 10th and Patton for the timeline you are presenting.
I did not say that it was impossible for him to be there. I said it was impossible for him to get there on time on foot. There is a difference.
Agreed, I was assuming he made it on foot but didn't specify.
This has Oswald leaving the house at 12:57 PM.
Is that also impossible?
This has Oswald leaving the house at 12:58 PM.
Is that impossible?
Yes on both counts IMO
How is it "impossible" that Oswald left the house at 12:58 PM
This seems like quite an extreme statement (IMO)
You must have a really good, solid reason for believing it's "impossible", particularly when you have no idea of the speed Oswald was moving. Roberts gives the distinct impression he was in a big hurry - "all but running".
According to Google Maps the distance between Oswald's rooming house and 10th and Patton is 0.8 miles.
At the not impossible speed of 6mph this distance can be covered in 8 minutes
At 5mph it can be covered in less than 10 minutes.
These are not impossible parameters
And what if Oswald only needs to be there 30 seconds beforehand, at 1:09 PM
merely 30 seconds?
Markham said she watched him crossing Patton and walking to the location of the shooting. That distance alone (from Patton to where Tippit stopped him) took - according to a video posted by Bill Brown - around 30 seconds to walk. Remember Benavides who waited in his truck for an estimated 45 seconds until the killer disappeared on Patton?
And then there was the interaction with Tippit, before Tippit got out of the car and was shot. How long do you think that took?
Fair enough.
One minute seems a more reasonable estimate.
These things can't be known with exact precision, hence the need for a range of times.
I agree. That's why I prefer my own timing of the walk which was 12,5 minutes. If Oswald was on 10th street at 1:08 (which computes with Markham's arrival, after walking one block), then he must have left the rooming house at 12:56 at the latest. I don't believe that happened.
That's not a range of possibilities.
That's just you deciding what it is.
