Not sure on the filing number. I'll definitely try to find out. Security was very lax compared to the last time I went. Seriously, walked up with my backpack that has 7 individual sections and when I went to open one of the smaller pockets the kid, I say that because he looked 15, said they only need to look inside the main pocket, that was it. Exactly one year ago same place the lines were moving slow because it seemed like every one with a bag or purse had their bag gone through extensively. Another thing to note was the signage. The sign stating no firearms was marked Qwest Field Event Management. There was no other promoter or 3rd party listed anywhere, so as I read that it's a public facility so they technically can't tell you not to carry. It's like the light rail, signage at the station says "No Illegal Firearms" but on the train itself it says "No Firearms"...and there's nothing "illegal" about my sidearm nor how I choose to carry it.
