How do you introduce evidence legally? Just because they have it all does not magically mean they can just arrest and hang them all in one day.
We are a nation of laws and not men. If this is something that bothers you then I suggest taking a break and reading up on some history, maybe of nations that went through periods of lawlessness where they killed people just because someone in the highest position said so.
I don't even know why I should to type this out your likely a shill. You seem unrealistically impatient and incapable of seeing the bigger picture of what is actually going on.
