I have a better idea:
“I’ll be happy o answer your questions after I consult with my lawyer. You do not have permission to be here, without a warrant. Do you have ine? No? Please leave.
And video record it.
Appreciate your bravado and sentiment...
However, the ATF would be back at your door within the hour with a warrant...
Non-voluntary surrender will probably result in arrest and prosecution.....
As I understand it, they not only need a warrant—they MUST have the county Sheriff with them.
Talk with a lawyer BEFORE you do that.
That tactic can get your house destroyed and then called “probable cause”.
