B'Tselem, Israeli Human Rights organisations and numerous Israeli soldiers deny Israel's protestations of fairness and innocence.

You call them liars.

Fairness Don.
States can only aspire to it.
Those who criticises Israel for insufficiency of fairness are free to do so, but as Bobad reminds us, most Israeli Arabs find Israel a good place or even the best place to be, and Freedom House identified it as "the only free country in the Middle East and North Africa"!

Innocence Don.
Israel does not claim to be innocent of any mistake or misjudgement.
It does deny the lurid crimes you accuse it of, and the above to not support you except a number of soldiers unrepresentative enough to be highly suspect.
