Yes, police can often see if you own a firearm, especially if you have permits or during a stop, through sales records linked by serial numbers or background checks (NICS) when buying, but they generally can't access a real-time national registry of all guns; however, dealer records are kept and can be searched by law enforcement, and states with permit systems might link gun ownership to licenses, potentially alerting officers during routine stops.

While there's no central registry, some states require dealers to keep sales records (which can be accessed by law enforcement), and others have specific laws about permit records, with most states making permit info private. 

What information do cops see when they run your license?

When police run your license, they see your personal info (name, address, DOB), license status (valid, suspended, revoked, restrictions), driving record (violations, accidents), outstanding warrants, and potentially criminal history through national databases like NCIC. They also check vehicle registration, insurance status, and any active restraining orders or probation/parole details, revealing much more than what's on the physical card, including past offenses and "hits" for warrants or other flags. 

Is every gun traceable?

Any firearm collected during the course of an investigation could yield viable evidence if examined. For forensic firearm examination specific evidence that can be recovered include weapon serial numbers and potentially fingerprints left on the weapon's surface.

It's generally not illegal to curse at a police officer in the U.S. because of First Amendment protections for free speech, but it can lead to arrest if the language crosses into "fighting words," threats, or disrupts public order, potentially resulting in charges like disorderly conduct or resisting arrest, depending on state laws and the officer's interpretation of the situation. While cursing alone is usually protected, actions like shaking fists, spitting, or making threats can remove that protection and lead to criminal charges.
