As off-topic as it is, I will point out that cleaning a firearm where you can been seen by people outside your house is both an invitation for someone to steal it, and an invitation for unwanted police attention.
Just because it is legal, doesn't mean it is a good idea.
I live in an open carry state; in fact here’s what the State Constitution says on the matter of arms:
Art II, Sec. 6. [Right to bear arms.]
No law shall abridge the right of the citizen
to keep and bear arms for security and
defense, for lawful hunting and recreational
use and for other lawful purposes, but nothing
herein shall be held to permit the carrying
of concealed weapons. No municipality
or county shall regulate, in any way, an incident
of the right to keep and bear arms.
But it was ALSO violation of the 4th Amendment: no warrant.
The *ONLY* reason that I didn’t file charges was because I was away and my landlady, who did interact with them, had far more right than I (and arguably it could be said acquiesced-to/invited their presence) — When I got there the situation was virtually defused, mostly because a police Sergeant I knew had time to get there [and calm the officers] before I arrived.
The point is that MANY police do not ever consider the law in their performance of duties: they merely follow orders.
