She had intent towards Hammond...
Why do you keep repeating this statement about her having intent, mummmy? We know she had intent - to give him some papers and talk to him. So what?
The first time I saw the video, I thought she had something in her hand and she was heading for Hammond.
But then, you didn't see her close up. , and I'm prepared to bet you didn't know that she would have had to go through tight security so couldn't have had a weapon. So, again, so what? Lot of other people who saw her close up left her alone and clearly didn't think she had a weapon or any intent to attack.
headed in an agressive manor towards Hammond, when stopped from reaching her goal she resisted and tried a third time while being removed....
No-one else apparently thought she was aggressive enough to need to stop her, and Field himself obviously decided it was perfectly safe both to leave her arms and hands free, and to let her go when they are outside. And what you can see in the video is her trying to escape from the man assaulting her, which is is perfectly entitled to do.
But do carry on ignoring reality, won't you?
