AS cassandra's daddy mentioned, TSA wants to fine the airline. That's typical gov't BS...hey, we'll come and break your stuff. Then, we will send you a bill for us breaking your stuff.
Not to mention, but I don't even think commercial aircraft even have door locks, so that in a crash, rescue personnel could still get in. So, basically, TSA wants to fine the airline for something they couldn't have done anything about, anyway...
