The PA routinely arrests Hamas members. On the daily. Locks them up or hands them over to Israel to lock them up for years. Isn't that already evidence?
Yes, that absolutely serves as evidence. I don't think what was written in the comment I replied to serves as evidence by itself though, which is all I was pointing out.
To be fair, the GP comment asked what one thinks about the possibility, and the parent comment provided some limited grounding. It’s a bit difficult to provide concrete evidence for a hypothetical.
