First, the Bad;
The Supreme Court Declined to take up a case that would have challenged an assault weapons ban in Illinois.
As I mentioned at another forum I belong to, declining a case is not a loss. It is a setback but also allows for a future case from another jurisdiction with better merits to be made at a later date.
Now the Good;
As usual the anti-gun democrats attempted to use the latest terror attack in San Bernardino as an excuse to add a number of gun control measures to an economic bill.
It didn't work.
You win some, you lose some. The anti-gun right crowd started hammering away in earnest back in 1968 after Bobby Kennedy was killed. They lost a bunch but they didn't quit and eventually succeeded in getting some pretty onerous legislation passed at the local, state and federal levels all across the country. If you're a gun owner in this country and you want to roll back any of these laws and enact more protections for your rights it's real simple.
Just do what the anti-gun rights crowd did and keep at it. There have been more legal successes for gun-rights in the last 7 or 8 years then there have been losses. Vote, organize, donate and don't quit.
It really is that simple.
