New member but long time lurker looking for some advice.

I'm working my way to law school to hopefully become a lawyer soon but the more I've learned and studied, the more I've come to believe that many in the criminal justice system are corrupt and repulsive. People like Kamala Harris (seeing how much power they have) have only exacerbated those beliefs.

I really do think law is my calling, but I want to make a difference and not be yet another shill. This prolly isn't the best place to ask, but how do y'all think I should go about making a difference, even a tiny one?
