This is why I think all lobbying should be banned, in combination strict campaign finance laws, and strict enforcement of those laws, no matter who breaks them (even if billionaire candidates do, or say the VP of the country. Put them all in jail if they do it).

Instead of lobbying, what you should have is just hearings. The companies could still be free to offer a witness for the hearing, but it's all going to be public, and it's going to look weird if all of your witnesses are corporate people or all are from law enforcement agencies, when debating a new issue/bill.

Open debates in public hearings where multiple politicians participate beat backroom lobbying deals any day.
