Just a thought here. Mre. Ramirez was a gardener and probably had traces of fertilizer on everthing he owns ( ammonium nitrate?). Can you say Timothy McVeigh/ Oklahoma City? I would rather be delayed than have some idiot bringing unscreened liquids and other potentially dangerous stuff on any plane I am flying on. The Flight 253 incident in Detroit should point out that the threat is very real and like it or not, our world has changed.
