"reasonable restrictions"
1st thing on the list is tracking and licensing. Followed by microstamping. Those are some of the worst and non reasonable restrictions i can think of. The most insane part is where you even show an example of systems like you proposed being used against citizens for no reason, yet still want to push and promote them. Oh but the cops will get in trouble! Because cops clearly and routinely are held accountable for their actions right.
Oddly enough you dont mention actual "reasonable restrictions" such as requiring a BG check on all purchases and opening NICS to the average person.
