I feel an important thing to remember is that the filming didn&#039;t start until the altercation began and witnesses confirm that she was using profanity.  I don&#039;t feel her actions are defendable because she was causing a disturbance and rejecting authority.  I personally wouldn&#039;t feel safe any place where people are allowed to behave belligerently like this woman did.  Disrupting behavior must not be tolerated.  
It appears that she was asked to leave the train only after she initiated a confrontation.  The profanity was addressed with a warning, the further repercussions after, well the elitist snob did that to herself.  

I wrote an entry about her on my blog, please feel free to view it if you feel so inclined:
