1. They lobby the legislature right, they can't lobby judges themselves.

2. Is there is any evidence that they are lobbying for more or heavier prison sentences to make more money, because that's a pretty serious accusation. I would think that the lobbying money is actually going to get politicians to choose their prison service over public ones or their competitor's private prison. I think that allegations that they are lobbying to get more people into jail is a serious and unsubstantiated one.

Prison guard unions are public safety unions. They aren't lobbying to get politicians to choose their prison service, their company. They're unions of government workers. The competitor would be private prisons.

> Is there is any evidence that they are lobbying for more

Obviously most of this is at the state level. I live in CA and know more about CA. We have private prisons, just fewer.
