How so?
Specifically, how does a background check lead to registration and why has it not led to registration thus far?
I'm just asking a question.
If you can't answer the question it's OK. I'll move along.
The "improved background check" will likely be trumpeted as a step towards keeping guns out of the hands of criminals, the unstable and the dangerous. The politicians involved will proudly bask in the glory of bipartisan compromise and development of a constructive solution etc.
Then either or both of the following will occur:
1. The improved background check will be associated with a database of all gun transactions reported. It will either be created in stealth or with some sort of assurance that access to the database is strictly regulated and completely unavailable to other agencies.
2. In time it will become obvious that the improved background check is not working, or not working well enough, because there are still mass shootings.
The argument will then be made that we must take the next step, universal registration, because there are simply too many unregistered guns. If do this, then we will be safe.
Knowledge is power and the government wants more of both. The founders did not trust government. Neither do I and neither should you.
