So..let me see if I got this straight

July 2016 - Incident "allegedly" occurs
December 2016 - Criminal Lawsuit Filed
June 2017 - "Alleged assailant" acquitted of all charges
And now... July 2018 - Suing United? Sounds like a $$$ grab to me.

My questions:
"No open seats", yet she was moved to another seat in the same row. Interesting contradiction...
How can you sue United when the assailant was cleared of all charges? So what are you suing United for? According to the courts, there was no wrongdoing?

Edit: This is just me thinking out loud (and it might be a little harsh, so sorry in advanced), but if someone was touching me inappropriately and there was an empty seat a couple of seats away or across the aisle, I would move without asking. Why sit there and endure this torment? Why not do something (the little that you possibly can do on an aircraft) to make the situation a little less tormenting?
