Here's what I don't understand about those who want to pass greater gun restrictions. I personally a. don't like guns b. own guns but I don't see that the answer is to pass huge gun laws restricting access to guns.
1. What do you do with the guns already out in circulation? Let's say you make semi-automatics illegal how are you going to round up all these guns and how are people going to react if the answer is to send law enforcement out to collect these guns?
I suggest something akin to compulsory purchase as used where land is required for civic planning. This would be expensive, but equitable.
The confiscated toys could then be decommissioned or, where appropriate, sent where they might do some good: the Peshmerga may be relied upon to turn them on America's real enemies.
2. Why would a ban on certain types of guns be more efficient than a ban on certain types of drugs? Drugs are consumed and then have to be repurchased while I already mentioned that guns are already in circulation which makes it seem like this would be an even more difficult task than the War on Drugs.
Illegal narcotics are in many cases addictive and, being illegal, are harder to trace than guns. Furthermore, their supply is undertaken by organised criminals highly accustomed to flouting the law. The same lack of cooperation from law abiding citizens who are being offered compensation cannot be assumed. Even if it could, the interruption of the further supply and proliferation of new guns would nevertheless be a good start.
3. Most of the mass shootings we see in data are gang related (We just see the non-gang related ones on the news). There have been 3 non-gang related mass shootings this year. 133 gang related mass shootings. If most of the mass shootings are gang related, I highly doubt they are going to follow the new laws or that it would restrict their access to guns. All it would do is create a larger black market for guns that would help more money flow to gangs.
As above, it cannot be assumed that law abiding citizens are "addicted" to guns in the same way as drug addicts are to narcotics, nor is there reason to suppose they would seek the same recourse to illegal supply.
The fact that many people are shot dead in gang conflicts is no good reason not to stem the tide of people shot dead outside gang conflicts, in my opinion.
