George Hutchinson's statement is too good to be true?

George Hutchinson's statement is too good to be true? Then it came to me and I should have spotted it earlier ...

Excerpt from George Hutchinson's statement:
'I stood against the lamp of the Queen’s Head Public House and watched him. They both came past me and the man hung his head down with his hat over his eyes. I stooped down and looked him in the face. He looked at me stern. They both went into Dorset Street. I followed them. They both stood on the corner of the court for about three minutes. He said something to her. She said: “All right, my dear. Come along. You will be comfortable”. He then placed his arm on her shoulder and she gave him a kiss. She said she had lost her handkerchief. He then pulled out his handkerchief, a red one, and gave it to her.'
There it is. Did you see his lie? No, and neither would any human because we don't perceive colour at night.

This is the physiological reason if you're interested:
There are two kinds of light-sensitive organs located in the backs of our eyes: rod-shaped and cone-shaped. Both rods and cones are sensitive to light. The difference between them is that the rods allow us to see in very dim light but don’t permit detection of colour, while the cones let us see colour but they don’t work in dim light.When it gets dark the cones lose their ability to respond to light. The rods continue to respond to available light, but since they cannot perceive colour, everything appears to be various shades of black and white and grey.

A little about coal gaslight:
Gaslights became brighter after 1885 with the invention of the gas mantle. I think it safe to assume that gaslights emitted a dull light even with the invention of the mantle, which I doubt were utilised in slum Whitechapel in 1888. Coal gaslight emits a yellow greenish tone and would degrade the colour red even if Mary Kelly and her punter were standing under a lamp post, which they weren't. The position of the lamp opposite no 13 (Mary Kelly's room) would not have cast light on the entrance to the court. So George Hutchinson couldn't have seen a red handkerchief from where, and when, they stood.

George Hutchinson may have seen a man give Kelly a red handkerchief, but earlier, under a brighter, and natural, light. 'He then pulled out his handkerchief, a red one, and gave it to her'. Hutchinson's critics are right. His observations are too detailed. He's lying, but why?

If Hutchinson's story regarding the red handkerchief is true, ignoring his stated time-frame, and he witnessed a man tie a red handkerchief about Mary Kelly's neck, then the symbolism of that action prior to her death is acute.

N.B George Hutchison spent all his money going down to Romford. It must have been for some other purpose than visiting Romford Market, which didn't/doesn't trade on Thursday.
