you focus on the wrong part here
we don't care about their "stock price"
in fact all I care about is the safety of that flight and you should too
note I said - he was and is a lunatic- and it was a good decision to remove him 
but the way they did it.... well, that's the issue - and that's where they made their PR mistake
I as a fellow passenger have the same right to have crazy people taken away....

but focus on their stock price??? really?  that's important to you as a passenger.....glad youre not in charge....
