"Florida Governor Rick Scott signed into law changes to school safety and gun access on Friday."
"The new legislation raises the age to buy rifles from 18 to 21, extends a 3-day waiting period for handguns to long guns, bans bump stocks that allow guns to fully mimic automatic fire and allows some school staffers to be armed."
"The NRA immediately filed suit to block it from taking effect." Because the NRA is showing its true colors. The NRA has become a threat to responsible gun owners. With their self-serving and legally flawed reading of the Constitution, along with absolute unwillingness to compromise -e.g. their Un-American behavior, the National Rifle Association continues with its primary mission of making money for itself with which to buy politicians and provide obscene amounts of compensation to management.

Repeat:

That the Second Amendment continues to be misinterpreted to the benefit of those in favor of gun ownership remains one of the biggest stains on our nation. The language of the second amendment is clear, and so is the intent. The Second Amendment provides for armed militias for purpose of protection of the state. Put another way - as a group we are allowed weapons to be used for protection of the government.
No reasonable interpretation allows me to have my very own goddamn machine gun, whether I use it for "hunting" or mowing down school children. In fact, the Second Amendment doesn't guarantee me the right to own even a water pistol. Instead, it explicitly allows the government to decide who can bear arms, and when. It provides for, even requires government regulation of firearms.
Or, as put by Supreme Court Chief Justice Warren Burger: "The Gun Lobby's interpretation of the Second Amendment is one of the greatest pieces of fraud - I repeat the word fraud - on the American people by special interest groups that I have ever seen in my lifetime. The actual purpose of the Second Amendment was to ensure that State armies - the militia - would be maintained for the defense of the State. The very language of the Second Amendment refutes the argument that it was intended to guarantee every citizen an unfettered right to any weapon."

For those of you who don't remember Justice Burger - he was considered conservative, very. He'd have made Stevie Bannon look like a daffodil-toting liberal. Basically he was a redneck's dream.
Well, except for his annoying tendency to state the truth. In this case, that you, me neither of us has a constitutional right to own a weapon whether it be firearm or butter knife.

If you want a gun I suppose you're going to have a gun. Just don't misquote the Constitution as part of your justification.
The Second Amendment is clear. Allowing convenient misinterpretation to the benefit of private gun owners requires massive sums of money and political clout. Enter the NRA and gun manufacturers, e.g. very wealthy individuals and groups, padding politicians pockets lest they might actually start enforcing the guiding documents of the United States of America.

Rather than using their positions of power to be part of the solution, rather than seizing on a true opportunity to make things better - the NRA and like groups instead continue with their hate-filled rhetoric, pushing self serving and blatantly incorrect legal arguments to the massive benefits of their wallets.
And in so doing absolutely positively 100% guaranteeing more massacres.

The NRA is no longer concerned with the rights of gun owners. The NRA has become a money-making machine with main purpose being to pad the wallets of management and pay off politicians. In fact, by showing absolute unwillingness to compromise they are becoming a threat to responsible gun owners. Add in a fringe element - NRA supporters actually threatening children who survived the latest school massacre - and the group is becoming the face of political peril (regardless of your thoughts on firearms most of us realize how disgusting and flat-out chicken it is to threaten these kids. Yet the bigwigs, the millionaires in management at the NRA who have become rich off your dues are strangely silent.)

At some point the scales may tip, and politicians continuing to accept money from the NRA will be finding themselves un-electable. By continuing to show unwillingness to do the right thing, to become part of the solution, the NRA will devolve into a small, unimportant club of haters.

Responsible members should demand immediate change or separate from the organization. The NRA is becoming a very visible reason for increased gun control. (I am fully aware none of this will happen. What WILL happen is things will settle down again, we'll all kinda forget, and instead find something else to concern ourselves with. God knows there's enough other stuff to worry about.

Then another massacre will happen a bunch more kids shot to pieces. There will be much crying and gnashing of teeth. Again. The NRA will continue its convenient misinterpretation of the Constitution will continue to blame everyone except those responsible and will continue to pull in massive sums of money with which to buy politicians and shower on management. The circle will keep going round and round. The only winners in this uniquely American tragedy will continue to be the wealthy elite on the top rungs of the NRA. Laughing all the way to the bank.
And once again, and again and again - the rest of us will be left to try and rationalize our part in pumping eleven bullets into a fourteen-year old girl who's biggest sin was going to school on an unlucky day.
