If the PD's refuse to enforce, that's on thing. If the Supreme Court finds some or all of this unconstitutional, that's another. But, if parts of it sticks, compliance is voluntary. I wouldn't be leaving the house with items on the new list, but waiting out the insanity to let it pass, with new conservative government at the helm. Many hunting friends are LEO's and they believe house searches looking only for outlawed items will be rare, unless a warrant is issued for other investigations unrelated to 2a items. Resources are thin as it is and the danger to LEO's is too high for this activity.
