Why was it so easy? Because he never had a criminal record. A gun range is just a gun range. The owner who got those messages is by no means an authority figure of any kind. I've had times when I'm not all there and people can make rash judgement calls. My bosses at work thought I was on drugs (friend told me). I was just tired from waking up early. If that's all it takes then do I need everyone who has known me to be interviewed before I purchase a car or a knife (look up UK knife homicides)?
Please convince me that banning guns or otherwise would have stopped this guy from getting guns. Our government tries to ban things ALL the time. It simply doesn't work. The criminals always break the law and get them.
In fact if we banned guns a few things would happen based on what is happening with our drug ban.
1. Gun prices would skyrocket because they are illegal. (I know this sounds awesome to you, but hold on)
2. Cartels around the world would see an amazing profit potential shipping in illegal guns and selling as many as possible.
3. Entire new criminal organizations would be created and expanded thus giving them more money and power.
4. Criminals in order to afford them would commit MORE crimes in order to afford the HIGHER priced guns. This is why the drug ban is so terrible and hurts far more people who aren't involved at all.
If legal "Drug A" costs $10, I have to do $10 worth of crime. If "Drug A" is illegal and now costs $100, I have to do $100 worth of crime (more people hurt). This is what would happen if we ban guns.
We can't police 12,000 miles of borders and coastlines. There are precision machine tools all around us, so criminals will always be able to make guns and ammunition with ease. Police in DC seize home-made guns about 1 in 5 times.
