Before the thread gets totally derailed, here is my take...

1) the use of foul language never helps with anything - and trust me, I've lost it plenty of times myself, so I know of what I speak.

2) AA Flight Attendants are problematic - so are the UA crews. They are often unprofessional, mean and will use security nonsense to do anything they want. I actively avoid both carriers, and you learned a hard lesson why. Next time, find an airline whose staff have an interest in treating passengers like customers - you can choose from Continental and Delta, and I think that's pretty much it for the mainline carriers.

3) The cop was just being a bully - and no surprise there. You can file an official complaint against him and it will become part of his permanent record - do this remotely in case he decides to arrest you for the swearing/riot charges

4) If you have money to burn, hire a lawyer to send a nastygram to both AA and the MWAA cops - the lawyer should be able to push AA to either offer some compensation, or at least make them consider how their crew over-reactions are starting to annoy customers and cost them some business

5) if you don't want to spend anything on this, write AA yourself...while it is appropriate to point out the FA's gross overreaction and abuse of authority, it would help to apologize for your use of a cussword. A well placed mea culpa never hurts.

6) you can sue, but it will cost alot of money and I'm not sure you would get much more from either party than a well written complain letter and official complaint/reprimand for the cop would deliver for you

7) Cursing is free speech and you can curse all you want - any local/state ordinance to the contrary is probably un-Constitutional. However, exercising your 1st Amendment rights does not always resolve customer service disputes in your favor
