‘do we really want to set a precedent that state and local officials can be held criminally responsible for failing to enforce Federal law?”
It’s already been settled by federal courts, including the USSC, that state and local governments cannot be drafted by the federal government to enforce federal laws. States and local governments are sovereigns.
Exactly, and with good reason. So, while sanctuary cities are a huge problem, they should (must) be dealt with by their own states, not by the Feds. So, if Jindal wants the mayors of sanctuary cities arrested, let him send out Louisiana state troopers to take care of it.
Obviously there are Federal policies that could help curb the issue (tying Fed law enforcement funds to projects that include immigration enforcement is one easy one), but the issue ultimately needs to be fixed at the state and local level.
