It seems to have bipartisan support and the President supports it. People who exhibit "violent tendencies" would have their names flagged on an instant name check to purchase a firearm. It seems reasonable but how would you enforce it? My guess is that people who were (arrested for?) convicted of violent misdemeanors and spousal abuse would be flagged and so would every Veteran who admits to the violent tendencies associated with PTSD. Are we ready for that?
This is a red flag law. I did not find anything new being proposed by Congress. If you have seen it, could you share the link? I'm pretty in favor of this nationally, but I don't know how it relates to what you mentioned..
Red flag law
From Wikipedia, the free encyclopedia

States with red flag laws
In the
United States, a
red flag law is a
gun violence prevention law that permits police or family members to petition a
state court to order the temporary removal of firearms from a person who may present a danger to others or themselves. A judge makes the determination to issue the order based on statements and actions made by the gun owner in question.
[1] Refusal to comply with the order is punishable as a criminal offense.
[2][3] After a set time, the guns are returned to the person from whom they were seized unless another court hearing extends the period of confiscation.
[4][5]
Such orders are known by various names, including "Extreme Risk Protection Orders" (ERPO) (in
Oregon,
Washington,
Maryland, and
Vermont); "Risk Protection Orders" (in
Florida); "Gun Violence Restraining Orders" (in
California); "risk warrants" (in
Connecticut); and "Proceedings for the Seizure and Retention of a Firearm" (in
Indiana).
[6] As of August 2019, 17 states and the
District of Columbiahave passed some form of red-flag law. The specifics of the laws, and the degree to which they are enforced, vary from state to state.
