I hope to be hired on as a Conservation officer in June and I know that if you send in the papers with unknowm on it your local law enforcement will be at you door. Falsifing a federal document will where they will start so play it safe and send them in correct but at the end of the time alotted.Also the police cannot enter your house without probale cause and if you are believed to be falsifying documents thats probale cause. The only way they can see your guns is if they were called about a domestic disput involving the guns or a domestic and the guns were visible IE. not stored properly. However if you are thought to have commited a fish and wildlife violation us CO's can enter and search without question but that also requires a call that is justifiable with another form of evidence. Besides CO's have already said they won't enforce the FAC laws until everything is finalized with the system.
Sorry to bore you with my interpretations. hope this helps someone.
