This has been proved beyond any shadow of doubt
I refute that Jim.
I have shown how the nurse's, doctor's and journalist's accounts of those events show no such thing.
Nor did the testimony of the soldiers who came forward at the time.

I acknowledge that many claiming to be witnesses came forward long after, but I regard them as unreliable.

There is no evidence that IDF knew what was to happen.
There is no evidence that they observed it, and good evidence that they could not have.
The flares would not have assisted the massacre which would have happened with or without them.
