By refusing to enforce they would not allow prosecutors to bring cases of violations against RFRA like your pal Terry there.
The city of Indianapolis (yes THE CITY) made the proclamation when the legislature (representing the city) made and signed the proclamation along with Mayor Ballard also making an official proclonationx
And as I said - Indianapolis doesn’t actively enforce immigration law here - sanctuary city in all but word.
First off, Who would not allow prosecutors to do this? A county prosecutor is a elected position and nobody has the power to tell them what they can and can't prosecute. Second off, nothing in RFRA allows any prosecutor to "bring cases" for it's "violation". The statute provides a defense for defendants being charged with certain civil rights violations.
