No, I don’t think you’re completely understanding the undertaking and consequences here,
The NY Safe Act was an AWB passed in New York, it had a provision where if you had an assault weapon you had to register it with the state, let’s see how that worked out
“That data shows massive noncompliance with the assault weapon registration requirement. Based on an estimate from the National Shooting Sports Federation, about 1 million firearms in New York State meet the law’s assault-weapon criteria, but just 44,000 have been registered. That’s a compliance rate of about 4 percent.”
This is a case where noncompliance is a felony. This is the “opportunity to turn in their guns peacefully” part. Only 4% turned in their guns peacefully. So a gun confiscation nationwide means millions of felons, and enforcing the law means sending police out after them.
To give you an idea, our current prison/jail population is about 2 million. If you don’t see a problem with the plan your talking about I hope you also don’t complain about our overcrowded prisons.
