You asked a question, were provided with info into a)why you alarmed b) the tsa process (as bad as it is for the psngr) and c) given advice to avoid or limit the issue in future - the snippy "not so helpful" is really inappropriate IMO given the post and info in response to your request. You can always do your own footwork as tsa.gov if you prefer.
