heres what the idaho constitution says about firearms confiscation..
SECTION 11. RIGHT TO KEEP AND BEAR ARMS. The people have the right to
keep and bear arms, which right shall not be abridged; but this provision
shall not prevent the passage of laws to govern the carrying of weapons
concealed on the person nor prevent passage of legislation providing minimum
sentences for crimes committed while in possession of a firearm, nor prevent
the passage of legislation providing penalties for the possession of firearms
by a convicted felon, nor prevent the passage of any legislation punishing the
use of a firearm. No law shall impose licensure, registration or special
taxation on the ownership or possession of firearms or ammunition. Nor shall
any law permit the confiscation of firearms, except those actually used in the
commission of a felony.
