What did Amy Klobuchar know about this?

First, some brief background. I have a Minnesota Permit to Carry a Pistol, and I generally carry openly, which is legal. On Tuesday, January 31, I was handcuffed, disarmed, and removed from the Edina branch of the Hennepin County public library, in direct violation of Minnesota statute 624.714, Subd. 23., by the Edina Police Department at the direction of the head librarian at that branch. For specifics on the incident, please see the thread here. I immediately contacted an attorney, who had the situation straightened out and my trespass warning rescinded within 24 hours. However, in researching the incident, I came to find out that the Hennepin County Attorney's Office had instructed the library to post signs prohibiting "dangerous weapons", in spite of the above cited law.

Amy Klobuchar is the Hennepin County Attorney, and is currently a candidate for the U.S. Senate. I would like to know if she personally directed the library to post the signs, her underlings directed the library to post the signs with her approval, or was this done without her knowledge. In the first two cases, I believe that these would be clear cases of a county attorney ignoring or violating laws that she doesn't like, instead of enforcing all laws equally and fairly which is what she is sworn to do. In the third case, I believe that this would be an example of a top official being clueless as to what her office and employees were up to. In any of these cases, would this be a person that one should support for national office? Regardless of how you feel about gun issues, what if the law that she decided to ignore or not enforce next was something that affected you directly? Would you want her doing this on a national level?

As of today, I have received no communication from Ms. Klobuchar's office other than my trespass recission. I know of no employees who have been disciplined over this, and the signs are still posted at the library. If anyone runs into Ms. Klobuchar, please ask her if this is how she would operate in the Senate.
