We know that you feel strongly about searches, Spiff, but that shouldn't prevent you from seeing that preventing weapons from going on board airplanes is a good goal. We merely disagree with how to achieve it.
On the ground, you can reasonably expect assistance from police officers as well as medical assistance. Both are not true in an aircraft.
If you think it's okay to carry something on board an aircraft just because it's okay to carry it on the ground, why not a concealed firearm? Want a Texan [state with most concealed firearms permits] to get on your plane with a gun?
