This in reference to Virginia, however other states may have similar laws, regulations, or policies that could be equally applied.
The number of business that have a no firearms allowed policy in the member agreement is growing, ie Costco.
This is assuming a valid CHP.
My understanding is, if there is a no gun sign, and if you are asked to leave and don’t, the police can be notified and you can be charged with trespassing. This applies to public and private property.
It seems to me that both the policy and sign serve the same purpose, to notify you that they do not want you to have a gun on their property.
Concealed firearm" means a firearm hidden from common observation, including a firearm hidden when it is observable but is of such deceptive appearance as to disguise the firearm's true nature.
Case in point. A man attempts to enter Costco, the greeter says, Sir, I believe you have a firearm on your person and store policy prevents you from entering, unless you are LE. If the man denies he has a firearm and enters and the police are called, do the police have the right to ask if you have any weapons or ask to search based solely on the greeter’s word just because the man may have been printing or because the greeter saw a bulge that could have been a firearm?
What burden of proof is needed by the person or establishment to show that the person in question has a firearm?
In Virginia there is no obligation to notify LE when legally carrying concealed, but I also can see why an officer would want to know if someone has a weapon.
