That's a false dichotomy.
You know you're wrong about that and just to be a nice guy I'll prove it.
Ignoring
any observations of what those numbers represent we have a simple mathematical problem: Israel produces massively lower numbers as a percentage than other modern first world nation states. For that to happen mathematically you need to either
actually produce less (as in Israel is pursuing these cases less) or you need to inflate the numbers to lower the ratio (as in the Palestinians are making lots of false claims).
Those are the choices. Honest.
If you can't put up with that reality there is one more apolitical thing you could try. Prove the numbers wrong. This could be a corrupt data set and those to conditions are simply not true. Of course, that would require
real proof of other numbers being in existence and not just a simple ad hom smear on the source of the numbers we're currently using. The other way the numbers could be wrong is if we are comparing apples to oranges. Since this argument is predicated on legal systems being similar enough to compare, if you can prove that's not the case the comparison falls apart. Doing that is very simple; you need to demonstrate that the legal system in Israel is internally consistent across all demographics. If that's just their conviction rate, that's just their conviction rate so the options I presented simply don't apply.
Hopes this helps with your research.
