It's not aimed at criminals. It's aimed at law-abiding citizens who may accidentally run afoul of the law, thus making them criminals. It gives the authorities the legal means to thereby confiscate their weapons and prohibit weapons purchases - for the rest of their lives.
Agreed, and hoping I was not being rude or flippant in my initial response. More of trying to show the Karens that they are doing something but, as you say, it is aimed at law-abiding citizens who may accidentally run afoul of the law. I can imagine seeing all sorts of arrests and charges brought on the grounds of this law being thrown out or resulting in 1 dollar fines if there is any sanity remaining in that state.
