These laws might be called "liquor control," and they don't work. Most people in the state find them incredibly silly. (Derisive references to 19th century blue laws are common.) Obviously they don't stop drunkenness. I went to Gettysburg College, a little private school near the state line. I can tell you for a fact that people wishing to buy a lot of beer and get very drunk simply drove to Maryland and bought entire kegs of a very low-quality beer called Natural Light. (From the taste, I imagine it's a combination of rice water and human urine.) PA's laws certainly didn't prevent frat bros and other students from getting extremely wasted. Yet these laws exist and they drive up the cost of beer and other drinks for responsible users of alcohol statewide.
It's interesting that many of the same Americans who believe (rightly) that control of alcohol or marijuana have zero effect of consumption on those products nevertheless believe that prohibition could be applied to certain types of firearms, especially since alcohol has killed more people, far more, than guns ever have.
If you read one thing from this post, read this. It's a great website, and it points out one of the many many problems with gun control: that most gun control advocates don't know .223 Remington from 5.56 NATO. The people who wish to take the property of their fellow Americans, or restrict access to certain types of property, know next to nothing about that property. This is odd. I wouldn't allow a garbage man to tell my doctor what to do (or vice versa), yet it's the people who have never fired a gun who get to dictate what shooters can and cannot own.
Of course, any appeal to reason is useless, because it is predicated on the idea that politicians, or even some members of the public, make decisions based on reason. Politicians, despite their job descriptions, are concerned only with themselves. What matters isn't issues; it's elections. There are exceptions, but they are rare. Look at any politician's career: he didn't get where he is now by doing what he thought was right; he did it by doing what the majority thought was right. Members of Congress like Dianne Feinstein aren't stupid. They know that rifles like the AR-15 aren't used in the majority of gun crimes in this country. But bills like Feinstein's have nothing to do with preventing gun crime and have everything to do with people like Dianne Feinstein.
Let's take a look at a practical example of one bill which was passed in 1994: the Assault Weapons Ban. Under said ban, which sunset in 2004, the following weapon was illegal:
This one, however, was not:
In reality, these weapons are the same model: the Ruger Mini-14, featured in the above link. They fire the same cartridge at the same rate. Under the ban, they would also both be limited to the same magazine size. The only difference is the furniture.
Even a gun control advocate has to wonder about a law like this. If, as was stated, the '94 ban was about protecting people, why exactly was a gun like the Mini-14 allowed in one configuration, but not the other? Republican opposition? Maybe, but unlikely, since Republicans at the time didn't want the first model banned at all. Confusion? Possible, but Feinstein, the author of the bill, isn't an idiot. It's not unreasonable to assume that she knew enough about guns to realize that these weapons are equally deadly.
I'll offer an explanation: Feinstein and her cronies don't care even slightly for the safety of Americans.
The Assault Weapons Ban of 1994 was pure politics. Feinstein got to be famous at very little cost. She didn't really do anything; "assault weapons" were still very legal. But she got her name in the papers and got reelected. Even if you support gun control, your own people in Congress are lying to you, and they are using your lack of knowledge about firearms to do it.
One might ask why I would tell people this, since I am very obviously against gun control. The truth is, I'm not a politician. I'm not going to lie about how weak the AWB was and how weak future laws will be. Some might use this information to try and create laws that actually do ban guns. But I have a theory about gun control advocates. This theory states that the most anti-gun person on the planet can be turned by a little information and a fun and educational trip to the nearest shooting range. Guns aren't evil. They're tools. They're the embodiment of mind over muscle. They're a useful item for protecting your family from potential threats. They're capable of putting food on the table. They're plain fun. Some people misuse them, it's true. But some people misuse cars too, and we don't ban them because they are extraordinarily useful. Like guns, they are not designed for killing (you read that correctly), and the vast majority of people use them responsibly. That is why they remain legal. Are there limits? Yes. Similar limits to those which already exist on firearms.
The best weapon against evil and coercion are not AR-15s and AKs (though these are also effective tools against certain kinds of evil), but knowledge. Educate yourself. Understand firearms and respect them as tools, which, in fact, they are. Will it change the outcome of the legislation in Congress? No. Congress does not reason; it uses force and takes what it wants. (Let's be honest: if it didn't, you wouldn't be paying your tax bills every year.) But that doesn't mean you should accept it at that. They can pass laws, but they should not ever be allowed to get away with fooling the American people. That, unlike restrictions on magazine size or which stock to put on your AR, is something on which Americans may actually agree.
