Can anyone tell what that is? It looks like it could be a person holding a rifle, but that would be a convoluted "no guns" sign.
At the bottom of each of those doors is what looks like a circle with a slash through a gun and knife.
According to this thread, it is a gun free zone. http://forum.opencarry.org/forums/showthread.php?37817-Washington-Businesses-that-Ban-Guns
Then there is this from handgunlaw.us:
No Firearm signs in Washington have no force of law unless they are posted on property that is specifically mentioned in State Law as being off limits to those with a Permit/License to Carry. If you are in a place not specifically mentioned in the law that is posted and they ask you to leave, you must leave. If you refuse to leave then you are breaking the law and can be charged. Even if the property is not posted and you are asked to leave you must leave. Always be aware of the possibility that responding Police Officers who may have been called without your knowledge and may not know the laws on trespass etc. could arrest you even if you are within the law.
"No Firearm" signs do not have the force of law in WA. They may have a "no guns" policy but just didn't post any signs.
In the malls I’ve gone to (including my prime one, shot up a few years ago in another incident), I’ve never seen any signs posted in all my life. Nor for all the other rules they have. They can be found on websites.
