It would be laughable if it wasn't so pathetic and no doubt a stressfull experience for the mother. I'm not an expert on explosives but does any known explosive look any thing like milk (breast or otherwise?) And if she's prepared to drink any of it, let alone give it to her child, erm doesn't that prove it?
I understand the need for mothers to 'espress' the milk, but what the hell is wrong with breast feeding in the aircraft? The only person who could possibly see anything with out deliberatly craning their necks is the one sitting next to her (husband/partner?) and a stragically placed blanket should surfice.
When I was staying in Florida once, a program fuzzed out the back view of a womans breast (ie what you could see under her arm!) I mean, the crap and the violence that America has peddled in films to the whole world and they're worried about that! Something definetely not right.
