Mikey Idaho, "Welcome to the Club," as they say.
Idaho Falls' Firearm Code fits mostly in-line with Idaho State statutes. A bit overzealous (in that they duplicate much of existing Idaho Code §18-3302) in my personal opinion, though.
Here's a link to Idaho Falls Firearm code:
The part in Idaho Falls Code (IFC) §5-14-2 noting:
"...that any person shall be allowed to carry any of the above weapons in the places mentioned above on securing a permit from the Bonneville County Sheriff"
would be better served when worded as follows:
"...that any person with a State of Idaho Concealed Weapons Permit per Idaho Code §18-3302 (or similiar permit from other States which the State of Idaho recognizes) shall be allowed to conceal carry any of the above weapons in the above-mentioned places."
The reason for explicitly stating conceal carry is that a city can not pass any law, regulation, rule, policy, etc., pertaining to open carry.
IFC §5-14-11 is out of step with IC §19-202A, in that it declares someone guilty of a misdemeanor for the discharge of such when they are protecting themselves or another.
IFC's Chapter 5-14 would best be replaced in it's entirety by something similar to Caldwell's code (of which they changed it to 5 short days after I chatted with their Chief of Police on their outdated and/or out-of-sync-with-State-statutes code):
Hope this helps.
