Just push past the “security” nitwit and walk in. If they wrestle you down or arrest you,great! It might get on the news and open a can of worms.
That would be my option also. The “contract security” (AKA: rent-a-cop) goof won’t be held responsible.
Even better, and especially in OK, just keep you hand on your weapon and tell them, “I’m coming in under authority of the US Congress.”
Of course, there should be some consideration of the 4th Amendment in some fashion. But, 1865 took care of that.
They don't make people like that any more.
Unless you count slimeballs like "professor" Bill Ayers...
