Absolutely right let's blame the TSA.
The family had a financial agreement with the airline, they purchased services from the airline at an agreed price.
The federal government hurtles over the 10th Amendment and sets its self up on private property and gets between the airline and its customers.
If the airport or the individual airlines set up security checkpoints, that is one thing. That would be part of your agreement with doing business with them. If they violate you and treat you children like trash, you will no longer give them business.
The federal government monopoly and their TSA goons have no place there.
Yup, and the Airlines inform every passenger (it's on the online reservation form, as well as spoken during the purchase transaction should you purchase from an airline representative to "arrive at least 1 hour prior to departure". It's not a big secret, it's pretty much common knowledge.
While your arguement with regard to the 10th ammendment seems valid - the Surpeme Court would disagree with you, as well as Congress. This would fall into Article 1, Section 8 of our Constitution which gives the Federal Goverment the following powers:
The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defence and general Welfare of the United States; but all Duties, Imposts and Excises shall be uniform throughout the United States;
To borrow money on the credit of the United States;
To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes;
and so on, and so forth.
Thus, they are granted this ability. Pretty much every nation on the planet has security at the airport. Thus far, TSA has caught a few idiots who decided to bring back some C-4 from Afghanistan to show off to Ma and Pa, idiots who 'forgot' they had packed their loaded pistols, tons of pocketknives (I lost a few that way - and some were pretty darn nice too), as well as various insundries like endangered animals, drugs, large sums of money and chemical agents.
