Who else could have written it?

[Stephen Thomas]

Well we seem to be getting somewhere at last.

That'll be the day.

Well we seem to be getting somewhere at last. Except that K-453's suggestion that the writing meant that someone had a reason (not) to blame the Jews is not what it means at all.

Antisemitism was nothing new in 1888 and there must have been many non-Jewish inhabitants of Spitalfields/Whitechapel who resented new immigrants either because of their success or their poverty, or even because of their difference.

In my view the writer of the graffito - almost certainly NOT "Jack" in my view - had a grudge against someone in the dwellings (on that specific staircase), or against a nearby street trader.

The amount of Jewish traders in the street might occasion a disgruntled customer to opine it. Equally the close proximity of socialist meeting places
might cause a rival faction to vent it. Or it could just be happenstance, all are as likely reasons as cryptic killers message.

I like your suggestion about the likeness of a writing exercise, K.

However,take a walk around any city in the world, and you'll see graffiti - plenty of it. There doesn't necessarily have to be rhyme or reason for it, some people just like to vandalise. And in the days before the likes of spray paint were invented, chalk was the preferred option.

The only real hint we have from the message is, in my view and that of several others as discussed on the other Chalk thread, that the writer was a local and/or home grown Englishman.

Cheers,
Adam.

If the killer did not write it - who else in the neighbourhood could have a reason to (not) blame the “Juwes” for whatever?

The description “round schoolboy’s hand” gives me the idea the strange sentence might be some writing exercise for pupils. Or a punishment, like, “Write 100 times, ‘I will not throw my litter on the floor.’” And the kid wrote it, or a parody of it, on the wall after school.
