What I am try to say is that exemptions listed under the preemption statute state that they still can not restrict the possession
of a LCH holder.
However, except as provided in subdivision (5) concerning a
building that contains a courtroom, a unit may not prohibit or
restrict the possession
of a handgun under this subdivision in a
building owned or administered by the unit if the person who
possesses the handgun has been issued a valid license to carry
the handgun under IC 35-47-2."
Fine, lets look at the definition of possession...
"Definition of possession in English:
1. The state of having, owning, or controlling something:
1.1 Law Visible power or control over something, as distinct from lawful ownership; holding or occupancy:"
You see that it mentions "the state of... controlling" in the first, and "Visible power or control over something" in the second.
Now, lets look at the definition of "Restrict"...
"Definition of restrict in English:
1. Put a limit on; keep under control:
1.1 Deprive (someone or something) of freedom of movement or action:
1.2 (restrict someone to) Limit someone to only doing or having (a particular thing) or staying in (a particular place):
1.3 (restrict something to) Limit something, especially an activity, to (a particular place, time, or category of people):"
So, what the state laws say is that the county may not "restrict (Put a limit on) the possession (Visible power or control over something)."
Therefore, restricting the intentional display, is hence, restricting possession.
