What about property purchases? Without a county domain registrar on titled property, it's your word versus somebody else's that you own your property. You won't want to buy real property since the government tracks that too (and for centuries) and it's publicly searchable. The government jackboots will say you don't own the land you stand on without that, just like the thugs of the InterNIC/ICANN do regularly with centralized DNS. In short, don't buy real property.
You'll also not want to buy a plane ticket, as those are tracked as well.
Don't open a bank account--your bank will regularly report about you, especially large transfers of money. Find a nice hole in the ground on your untitled real property and convert to metal. Or use Bitcoin if you trust the system enough.
Definitely don't use a cell phone--they can find you.
There are zero logical reasons to prohibit a database that maps gun metadata to the gun record (search by name is actually detrimental to proper investigations). I've heard lots of emotional reasons, but I haven't heard a single well reasoned logical argument. Just a lot of reductio ad absurdum.
Going way back, the 2nd amendment entitles US citizens to own firearms because it's supposed to be a government for the people, by the people. If the people no longer support the government, they can revolt (ala american revolution). At the time, citizenry owning firearms was sufficient for a revolution to be successful. See 3rd amendment, as well.
So, the 2nd amendment was really an escape clause for citizens if they no longer wish to support the government. It just happened to be written as a gun measure. Having a governmental database controlling gun ownership thus violates that intention.
Vehicles have to be registered, and so should guns. For essentially the very same reasons.
You can't hand wave it into being. I don't see the connection to a registry at all. So you're an evil dictator and want to kill that revolution, what good is a list of 150m individual persons? What good is the mapping from "identification number" to "gun owner"? Is it important which "guns" participate in the revolution? Can anyone tell that?
Let's imagine it's 1860, and the local ex-slave population is acting up. But, you have a registry of all ex-slaves who own guns. You drive around with a posse and confiscate them all before a popular revolution gets going. Is that in the best interests of the local people? Probably not, thus a registry in this context could be used to suppress the citizenry.
The same thing is true today, but realistically there is no way individual gun ownership in 2016 is going to be sufficient to for a population to successfully revolt. It's not like we are letting people own gunships. However, the 2nd amendment hasn't been updated to reflect modern reality. In a lot of ways, this boils down to an "originalist vs living constitutional" argument.
Why don't you trust the populace with their guns rather than ask the populace to trust the gov't with a registry? For X amount of bad things to happen (where X is a large number) you need a lot more coordinated or systemically encouraged action in the first situation whereas in the latter a few insulated members of the elite and a loud lobby by a few interest groups would suffice.
It's all about checks and balances. The second amendment gives some power to the people to revolt (in theory), as a check against government power. If the people need to trust the government not to do something unconstitutional (i.e. not confiscate weapons) for that to be effective, then the check is no longer useful and it defeats the purpose of the second amendment.
Using such a database to deny a citizen the right to purchase a gun would be one way, for example, but I don't see that mentioned here.
Nazi Germany, initially using "well intentioned" Wiemar law, in fact (the period after the WWI defeat was very chaotic and bloody). See this book by the #1 RKBA legal scholar for all the details: https://www.amazon.com/dp/1598131613/
The description also helps confirm this next example:
Any country they invaded with registration lists, including the Netherlands; perhaps the #1 US RKBA activist of the 20th Century got started down that path in basic training after WWII, when a refugee from there related an atrocity he'd witnessed, where a whole family was machine gunned in the village/town square after the head of the household couldn't produce a handgun the register said he had.
The above examples are particularly instructive since by definition you can never know who might in the future use such data for ill.
Soviet Russia if I remember correctly; in fact, if I remember correctly, there was not a single genocide in the 20th Century that wasn't proceeded with the pattern, aside from China, where the Communists instead dried up the supply of guns held by the population by imposing "rifle taxes" on the wealthy. Basically, their life was forfeit unless they supplied the Communists with a certain number of guns, and they moved heaven and earth to do that, not that it did them any good in the end.
Of course, the poorer the population in general, the easier it is to pull of such a gambit, or a registration followed by a confiscation, so many fewer have guns.
Communist Cuba, for sure. They came up with a catchy slogan, got too many people to register, confiscated the guns, and then gangs of them started having fun with their class enemies.
As noted elsewhere in this discussion, in smaller numbers for select types of weapons, with of course the option to remove them from the state, this has happened in California when the status of the obsolescent (but certainly effective, e.g. used by the recent Dallas cop shooter) SKS, and in New York State. Something like it might be playing out right now in Massachusetts as their AG decided to redefine their "assault weapons" law, but she's still changing her not actually all that official position on it (i.e. it's published in unofficial venues like the office's web cite, no proper rule making process was followed).
This isn't the 18th century anymore; handguns and assault rifles won't stand up to tanks and jets.
In many fights of this type (internal) victory doesn't necessarily require militia A defeating army (with tanks) B. It can come from militia A being a large enough PITA to warrant a change in plans, or gathering enough popular engagement and outrage to make a difference, or for members of Army B to say "hey I don't want to shoot (or be shot by) my neighbors in Milita A". FWIW I am not a proponent of armed revolt against our government, but I think your question regarding AR-15s vs M1 Abrams isn't capturing a possible/likely reality.
Edit: I should have been more general with the "you". Only the opposition to the gun database has succeeded. There's no general conversation about privacy; there's no coalition of pro-privacy orgs with a consistent view on what should and should not be stored in databases. Why is this?
uh, did he say he was?
i'm sorry, did i neglect to read half the article, or half his comment, where these things are mentioned?
