Easy for me to say from the peanut gallery (no new gun laws proposed in my state yet), but based on what I see as the summary in the press (best article I found was in the Christian Science Monitor) this is a mix of things I support and things I oppose.
On the positive side, better and universal background checks, measures to make sure those with mental health problems fail background checks, and stiffer penalties for gun crimes. But all of those would be better dealt with in a consistent way at the federal level than state by state. Strong background check rules in NY will just drive the bad guys over the state line to purchase their guns.
On the negative side, the restrictions on ammo sales seem screwy--how are they going to implement that? Are we going to see something like the Massachusetts FOID card?
The assault weapon ban is just silly. I'd like to see how they've written that to understand what it means for various firearms on the market now.
I'm ambivalent about the idea of limits on magazine capacity. At 10 rounds, and excluding .22's (allowing, I believe most current semi-auto pistols), it might make sense. I do see value in getting rid of the 30 and 100 round magazines. But 7 rounds is very restrictive, and it seems to me there are serious legal questions about retroactively banning magazines that were acquired legally in the past. There are probably legal issues with how "assault weapons" are defined and dealt with, too.
And I'm sure there are lots of other issues in the details, too.
Here's betting it's good for fundraising/donations/attention for both the NRA and the various anti-gun groups. And that the firearms manufacturers are already ramping up their marketing campaigns to use the fear of new rules to drive sales and prices up.
Call me a cynic.
