I think the CADL is a trial balloon to see if it is possible to circumvent existing law with the hopes of having an "authority" declared above State law... which would enable any "authority" to ban guns anywhere within the State.
And make no mistake... if it is shown that an "authority" is above State law every township, village, city, and whistle stop, will create a bunch of "authorities" who's first order of business will be to ban guns... all guns including guns carried under a CPL... within the "authorities" jurisdiction.
Then, within a few very short months, the entire State of Michigan will be blanketed with "authorities"... and all guns will be banned everywhere within the entire State.
I would suspect that some township "authorities" would ban guns and the carrying of guns anywhere within the township except upon property you actually own.
