1. This would just make people go around the system. 2. This is supposed to be the case now. Not everyone follows it. 3. At a measly $500 per gun (at the very, very low end of the range) even if you got just half the guns in the country off the street, the program would cost approximately $82 billion. Good luck getting that by Congress. 4. Yes, many states have this statute already, but more need it. 5. This is supposed to be done now, yet many municipalities have "found" guns get released through illegal ways (cops are involved as well). 6. Fine. Someone will simply come up with another way of making the trigger vibrate. Even if you make them illegal, people can 3D print them now. A criminal won't care about your law. 7. Worthless. first, there are 100s of millions of large sized magazines on the street. You'd drive up the price of those. Then, they can be 3d printed. Lastly, anyone who has used a firearm can change clips in 3 seconds. 8. YES.
You think the Jews could stop the holocaust if a few of them had guns? In fact it's the opposite. So many blacks are killed by cops because of the fear that they own a gun. Further, the concept of the citizens rising up in todays world is a fallacy. It only works if you have a coordinated armed resistence and then you have Syria where pretty much everyone dies. It's not like Assad was scared off by the armed resistance.
I can't really transfer a lifetime of growing up in other cultures while having a strong tie to the US via cousins and other family there. It is not complicated, when people have poor mental health in general, the outliers get worse. In my younger days/later 20s I backpacked around the US. I was a good listener, people of all ages teens to 70s just wanted to talk and be heard. At home in Ireland and some childhood in Denmark, people were friendly but had nothing like the deep longing to be heard. The scale and same-sameness vanilla of the US in the modern era (compared to the rest of the world) has a lot to do with it I guess. If everyone has access to decent mental health care (not shrinks looking to keep you on the couch for 5 years or 'churches' run by psychopaths too often), a rising tide raises all ships.
Say someone I know appears to be having difficulty adjusting... what would be a good source of help for that person? It is almost axiomatic in the U.S. that mental healthcare providers have serious issues of their own and make more money if the patient keeps coming back.
Enjoy your re-writing of history. Here are the facts... In 1930s Germany the few Jews who still had guns were able to stop brown-shirt thugs from harming their homes and businesses. Many of these individuals eventually left Germany prior the war. There are many instances of black families stopping KKK members and red-shirts from burning their homes in the time period of 1880 to 1970 by using guns to defend their home-steads. North Carolina history is full of citations of these incidents. Guns are very useful for defending your home and business against local thugs organized by politicians to harm you. These incidents of organized lynchings, burnings, etc. are generally "illegal" under the laws in a country. Nothing stops these incidents quicker than a few bullets from an armed citizen defending themselves. It is a different story when the federal government in the country sends in heavily armed federal troops to establish order. These actions are generally legal under the laws of a country (but in some instances driven by corrupt evil dictators).
