What gets me is an Officer can say to your face "You are not under arrest" but then handcuff you, take you someplace against your will, and detain you there without access to a lawyer.
How can that possibly be the conduct of Officers in a free country?
I could even understand if the Officer just plainly said "we can not let you board this flight, you must leave the airport" or something similar. But handcuffs and detention even though you are not under arrest is insanity.
