Usually that believe stems from the fact that those people explicitly announced they would do it again. And again. After being sentenced. In front of a judge.
I would still rather have them sentenced for the crimes they’ve committed - even if sentenced harshly due to their unrepentant disposition - than for the crimes they may commit in the future.
We are all hypothetical criminals and I would prefer that the state not have that freedom to lock people up.
I don't think most people have claimed they will commit a crime in the future. Not necessarily for climate protests, but in many cases in the US we do this same thing too.
