Heller v. DC was a 5-4 vote.
Within four years if a single Justice among the five die and is replaced by an Obama offering, then the SCOTUS will quickly hear just about any case involving gun rights and just as quickly reverse BOTH of the recent pro 2A SCOTUS rulings by the same 5-4 vote, and probably rule that the ownership or possession of any kind of firearm by anyone except the military, police or government agents as "unconstitutional", which will be followed by total, nation-wide confiscation.
One could surmise, and hope, that the SCOTUS (at least the 5) refused to hear the case because they expect better ones to come down the pike in the near future, AFTER any gun legislation is passed by House and signed by the President, and challenge cases filed by pro 2A groups. One would hope they'd make the definitive 2A re-enforcing decision then.
Just like in England, the "2nd civil war" will never materialize, IMO, because save for a few scattered groups of "organized" militia, which would be quickly neutralized by the US military, Federal agents and local police, most Americans will rely entirely on the ballot box and the courts and would never take up arms to fight their own government. Unlike the Islamic militants who started or hijacked the "Arab Spring" movements in various Mid-East states, the Michigan militia and other like minded groups do NOT have foreign governments supplying them arms in secret, nor do they have foreign fighters coming in to fill the ranks depleted by combat.
However, just like in England, gun violence will increase because criminals have never cared about gun regulations and they will have free reign in a country that places a "Gun Free Zone" sign over its entire territory. What also will be banned is any free speech rights, even for "educational purposes" which describe how to make weapons of any kind, not just firearms, just as it now is in England. Oh, did I mention that three years ago the English Bobbies had to start carrying submachine guns to defend themselves against criminals carrying automatic weapons?
In their zeal and willful ignorance to disarm themselves and the rest of us, gun banners seem to forget one fact: the 2nd Amendment ends with the statement "shall not be infringed". But, since the Democrats in the South began infringing the 2nd Amendment after the civil war to keep guns out of the hands of former slaves, infringements have been increasing at a regular pace.
The infringements are always proposed as "reasonable" solutions but end up never being reasonable, certainly being repressive, and not being effective in achieving their stated purposes. The 1984 assault rifle ban never slowed down the number of mass shootings, and NO gun regulations anywhere in the country have been effective in keeping guns out of the hands of criminals or the insane. Claims that places like Chicago can't control gun violence because the guns come from the surrounding states which have less restrictive gun laws are ludicrous. If bringing guns into Chicago is the problem, then why are the gun violence rates LOWER in the surrounding states that supposedly supply those guns? The Safe Schools Act and its "Gun Free Zone" laws only encouraged the insane to choose places so marked as their hunting preserve because, while insane, they knew they would not meet armed opposition to their plan of being glorified by the mass media for killing as many unarmed people as they can. And the media all too willingly use those insane acts to push their agenda. Senate bill 649 will not fair any better in those goals, even though it will make universal gun registration a lot easier to achieve after the next mass shooting.
Agenda? In recent times, those pushing for even more infringements have an agenda, which they aren't afraid to reveal during their more candid moments, or when they let their tongues slip. Their goal is confiscation of all firearms and repeal of the 2nd Amendment, if not the entire Constitution, because they favor the USA relinquishing its sovereignty to the United Nations (One World Government) and its gun control edics. In other words, they prefer Socialism instead of Rule of Law under the Constitution. And under Socialism THEY would be the ruling elite... for life.
What the the people commenting in the LSM echo chambers do not seem to realize, or care about, is that IF the 2nd Amendment, with its very clear "shall not be infringed" clause, can so easily be infringed then what hope do the other amendments, which do not have such a clear prohibition, have in surviving politically correct assaults? None at all. And, some day in the future, when they attempt to protest some act of the government that clearly violates what they feel is one of THEIR unalienable rights, not that they care a whit about the rights of people with whom they disagree, they'll understand. But too late.
