Here's what Wikipedia.com has to say about Constitutional Carry ...
"Constitutional Carry is a situation within a jurisdiction in
which the carrying of concealed firearms is generally not restricted by
the law. When a state or other jurisdiction has adopted Constitutional
Carry, it is legal for law-abiding citizens to carry a handgun, firearm,
or other weapon concealed
with or without an applicable permit or license. The scope and
applicability of such laws or proposed legislation can vary from state
Then the article proceeds to list states allowing Constitutional Carry, such as Vermont, Alaska, Arizona, Wyoming, Idaho (parts of), Montana (parts of), Illinois (parts of), New Mexico (unloaded).
Illinois (parts of)? Oh, really? "Illinois has no state preemption of local laws, which mean individual
counties may exempt themselves completely from state restrictions.
Several county district attorneys have stated that they will no longer
enforce state concealed carry restrictions. This effectively means that
these counties have constitutional carry. Extreme caution is urged
however as gun attitudes vary wildly by county, from pro-gun attitudes
in rural counties to extremely anti-gun attitudes in urban counties such
as Cook County (Chicago). Anyone considering concealed carry in
Illinois is urged to determine the specific laws in the county in which
they plan to carry." [emphasis added]
Many people, including I, believe that a County cannot make an effective law that is contrary to State law, but perhaps it can. Wikipedia.com does not carry the force of law, but it might offer an important clue that is not reported in the media.
The difficulty, of course, is that if you get arrested, then you have a huge and expensive legal fight ahead of you. Just to protect your rights.
