1. Don't trust SCOTUS even if the new golden boy makes it (watch TV today!). The precedents of the lower courts to support EBR bans might just stick with Alito and Roberts. Thanks, Anthony for your rhetoric in Heller.
2. When the AWB was passed it was cosmentic. Research then showed it had NO effects on any of the crime indices. Gun folks said - well, then get of bans. Anti-gun folks who were smart said the bans were not inclusive enough because the research showed:
a. There was enough existing grandfathered guns to supply a lot of the demand.
b. Equally efficacious guns without the the cosmetic features were still being sold.
The smart ones said thus there should be total semi bans and confiscatory polices on existing guns.
Of course, we had idiots who said just re-institute the old AWB, but the smart ones posed stricter laws. A nibble approach on mags and features was adopted and successful across many states (even pro gun) after each massacres moral panic.
Now gun folk chortle that the Supreme Court will - guess what DO NOTHING. They haven't taken a case and they won't. If they do, they might go for Heller like babble and support such bans. Why would they overturn the lower courts?
Folks say bans won't work as there are so many guns out there. History shows they won't be turned in as in some foreign country they still have WWII weapons buried. The regular guns in those countries show many haven't been turned in as happens in the USA in ban states.
However, a ban makes your gun useless for: self-defense (I used a forbidden weapon because I was in fear of my life - go to jail), competition, hunting, plinking, etc. If you have a fire and the gun is found by the firepeople - may go to jail. If you get into a domestic - partner or spouse says you have it - go to jail. Your toddler blabs.
Unless, you can get a SCOTUS decision (not hopeful on that) or Congress to act (FAT CHANCE), expect local bans to expand and expand, even in red states, after a massacre or two.
