Who was the most 'unreliable' witness?

[packers stem]

The reliability of witnesses has cropped up in a number of threads lately.For me the reliability should be based on a number of criteria and NOT A PARTICULAR THEORY
Many witnesses being described as unreliable purely because their evidence throws a spanner in the works isn't the way surely?
For me certain aspects should carry significant weight to their believability
1.Daytime or night time
2.Possibility of being intoxicated or sober
3.Sighted person being known to witness
4.Verbal communication
5.Eagerness to testify
6.Conviction in belief

For me the above if worked out in to some sort of points chart would put Caroline Maxwell so far out in front there's just no contest
As for most unreliable at the moment I'd have to go for Hutchinson mainly down to his convenient timing following the close of the inquest. Although he has 3 and 4, his lack of 5 destroys it...

The man who pretended to sell the grapes to Stride is, in my opinion, unreliable. Pearly Poll also, as she probably even lied on purpose.
If we go for "honest but unreliable", I'd go for Maxwell.

Schwartz is the most reliable witness, in my opinion. Simply because he saw something exceptional, easier to remember. But 1- I'm not convinced the assaillant said "Lipski" (Schwartz spoke no English and imo, could easily confuse a word for another) 2- the man he saw attacking Stride was probably not Jack.

Lawende fares very poorly under your factors.

Lawende fares very poorly under your factors.

I think Lawende said so himself.

Quite
Yet 99 out of 100 will state his sighting as known fact merely because it causes few issues.He claimed to recognise her clothing if memory serves...
PC Long in Goulston Street has to be right up there also
