What is the worry in this group with universal background checks for private sales?

17. Good points, But I own guns and have no worry at all who knows what I own and I don't care.....

if the government has a list.

Let be real, there is no possible way the government could or would try to collect guns. The first person to be collected on the list would start a social media nightmare with actual people marching in the streets. So not sure why registration would matter. And lets face it, there is not enough police in the USA to collect 300 million guns.

I agree that background checks might not make any difference. But knowing where criminals guns come from might be helpful.

Also, only 9,000 murders a year in the USA by guns. Stolen guns (50,000) could cover that number so people will get guns another way to bypass the UBC if needed.

Like you said, most mass shooters got them legally, so it will not stop those anyway.
