Video of Woman Dragged of Delta Jet in Detroit for Boarding Early

In Detroit Monday Morning a woman was dragged by her wrists off of a Delta Jet then arrested.

According to the USA Today,

She was removed after the airline had requested airport police help with the woman, "who would not comply with boarding and baggage check procedures at a McNamara Terminalgate," according to the statement. Charges are pending, according to the airport.

Video was recorded by a passenger who immediately shared it on youtube.

There are questions regarding this incident I feel are being willfully omitted.

#1 Did she go through the TSA security check?

#2 Did she have a ticket to board that plane?

If the answer to both of those questions is yes, how is forcibly removing and then arresting your customer the preferred way to handle this situation?

Thoughts anyone?
