You can have a fair and equitable court system, or you can have a fast one; rarely if ever both. True justice tends to be slow and steady and helps to account for public witch-hunts and reduce risk of someone innocent being. People always say, "Yeah well this one is obvious!" but that's not how justice works. It must be absolute. It must be there for the lowest of hanging fruit if it is to be there for the more nuanced cases just the same.
On the other hand, sadly, a slow and unfair one are not mutually-exclusive.
When I feel that I can't improve the world, I improve myself and focus on my family.
