I realize this is going to be a very unpopular post - but it also needs to be stated. It's not only up to TSA to enforce the rules (and agreeably many times they fail) - but it also falls on the flight attendants/flightcrew as well. If TSA fails at their job - and then the Flight Attendant/(s) see something that is a restricted item per TSA, it will get confiscated (if the flight attendant is doing their job properly) and that is entirely within their power and duties. If TSA ultimately fails... the buck gets passed onto the FA's who will enforce the rules - as they are ultimately responsible for ensuring security, safety and integrity onboard any aircraft they are on and qualified to operate. (This will even apply off duty). While this is never an ideal position to be in as an FA, rules are rules. ;) Hence - why it is very much appreciated that the travelling public educate themselves of the rules and of what is allowed and what is otherwise prohibited, so that conflict can be entirely avoided with respect to these issues inflight. Please remember your friendly FA's... just doing their jobs as required by federal law and federal aviation regulations. ;)
Explosive blessings, abundance and inspiration to you all!
