Can a non-resident alien own or possess weapons?

I received a question from someone who has the book, who was trying to help a friend.  As a reminder,  "having" the book will not help you unless you also "read" it  -- although there was a slight twist to the question on whether a non-resident alien could own other weapons -- if not firearms.   Federal gun law is very clear on the firearm and ammo issue -- a big "no" -- UNLESS -- you have a valid hunting license.  But as to any other weapons besides firearms (and ammo) -- you're clear to go as long as you obey the law.   So -- a non-resident alien could still own a Taser,  knife, or whatever else you can think of other than firearms, weapons,  and destructive devices.   Hopefully,  they'd also have (and read) a copy of my book -- so they know what they can or can't do with it.              [Florida gun law;  Federal gun law]
