ujm: In the Torah jailing is exceedingly rar
On the other hand, I understand that the mitzva for non-Jews to establish justice is a general requirement, not limited to specific punishments we have. This would make it OK (and a mitzva of assisting non-Jews in their mitzva) for Jews to be lawyers in any just system, like in USA.
Would it make sense for us to advocate for punishments closer to the Torah laws? Also, need to be more careful. In the classic case of Romans accusation of difference in Jewish law between a Jew and non-Jew paying half or full for animal damages: a Jew is obligated to watch his animal, so we presume that the damage is inadvertent. So, you need to look at society: if you can still millions of dollars and risk only monetary punishment (that you can probably pay from venture capital!), maybe this will not be a deterrent.
On the other hand, we are supposed to be light to goyim, so maybe explaining our approach – what is the purpose of punishment? do we need to always have imprisonment? etc – might help people look the issue differently.
Relevant to the topic – there was minimal public discussion of Trump’s prison reform. At the debate, Biden said that he wanted to do it (saying this before someone jumps in saying that there was no real reform) also but could not “because – Republicans”.
