I think the Texas provision of prosecuting prsons who leave the state for an abortion is unconstitutional, as it gives one state jurisdiction over deeds done within other states. This is one case where "states rights" works against conservatives.

The 'rewards' part of the laws was inspired by the old slave bounty system of returning slaves who ran away before the Civil War. What will happen is you will get people who will falsely accuse others with whom they hold a grudge, in order to collect the reward. Many of the person turned in as terrorists during the wars of Afghanistan and Iraq were innocent person turned in because the person who named them held a grudge against the person they turned in, and the U.S. paid them for this. I am not aware of any safeguards in place to prevent such actions from taking place. So, if you have a grudge against somebody you can claim they are transporting people across state lines for abortions and Texas will pay you money for making your enemies life hell.
