Jim,
You were given links to two films of mobs of Israeli extremists; one showing a roomful of people gleefully celebrating the burning alive of child victim of an arson attack - you question - without a shred of proof - the validity of that film.

The video was of a wedding party.
We a told that a photo of a dead child was being held up and abused.
If it was then the persons doing it were behaving despicably, but they were not government officials.
Also, it was impossible to discern what the picture was of.
To my eyes the subject appeared to be bearded, but it was litlle more than a blur. That is why I question the validity.
Here it is, http://www.dailymail.co.uk/news/article-3373035/Shocking-footage-Jewish-wedding-shows-guests-celebrating-death-Palestinian-baby-burned-alive-arson-attack.html

Anyway it was just ordinary Jews behaving despicably, if they were, so what was your point?
Are you claiming it as typical behaviour of Jews in Israel?
