I can find the female on male murder rate for most countries quite easily, and if it's not recorded, the number of women arrested for murder.
No such data is available for Ukraine - is that really the case? Or is it being hidden to keep people from rejecting the "refugees"?
How long would it take to run it through a translator?
People have the right to know if the "refugees" they are taking in are predisposed to murder them.
If they don't provide that data, "refugees" should be blocked.
