Yes, there is a reason to hear it.
The SCOTUS, as a matter of policy, will hear cases where there are differing opinions on the subject matter out of two or more of the US Circuit Courts.
In this case, we have exactly that issue. We have decisions out of the Fifth Circuit Court and the DC Court that the Second Amendment recognizes an individual right, and we have a decision out of the Ninth Circuit Court (where else?) that the Second Amendment is a collective right.
This sort of variance between circuit courts almost always will result in a properly constructed case being heard by the SCOTUS. There cannot be two sets of case law in the land in differing areas of the country.
I still disagree.
It is a RIGHT to bear arms.
NO dicussion to water it down is needed.
Why not?
That's pretty much what we have going on, where the Left Coast and Minority-Dominated entitlements' crowds are have installed Activist Judges who make law by tortured readings of the Constitution in order to enact the Liberal agenda.
The Law of the land is no longer based on the Framers' intent, nor the plain language of the Constitution; it's now based on the twisted interpretations that brought us to this point of taxation, socialism, and every sort of burden on individual freedom that was expressly forbidden in the Constitution to begin with.
The attacks by the ACLU, Atheists, sex deviates, minorities, and every other special interest have eroded whatever freedoms we once had, with no relief in sight.
When illegal criminals can be afforded sanctuary in locations of Liberal control, clearly in violation of Federal Law, why would the citizenry's right to be armed to defend themselves necessarily be expected to be protected?
This case will determine if yet another freedom is taken away (the right to bear arms).
You can bet that if the Constitution is upheld, the Liberals will be screaming about "the children" and "we must pass legislation to stop the killing", etc., and the push will continue to disarm those who abide by the law, and to remove the guns from the opposition to the socialists takeover of the entire economy.
