Guns will always be in the hands of the criminals and they generally don't purchase them legally or will ever be involved w/investigations/clearances. Concealed carry license takes longer. Couple days to purchase firearm these days (dealers/gun stores so slammed with business - non-concealed carry license) but the fast checks pick up negative profiles, if any, also. Probably varies from state to state.
Domestic abuse - most states have great programs/safe facilities in place and women's service organizations purchase/donate necessary items including furniture/pots & pans (have furniture cos donating) and these service orgs are throughout the US. I'm sure the need has grown w/Chi Com/political COVID like during the Great Recession.
