Dirty nutz...... what kind of scientific research are you looking for? Would you like to research the twin towers debris and rubble? Would you like to scower through it all and find plasma cut steel beams at 45 degree angles? Well guess what? The largest crime scene in the united states of america was packed up, gaurded by military personel with automatic machine guns, sent out of the country, and melted into nothing.....So what are you looking for exactly that would be justified as "scientific evidence"? Why dont you send a letter to Guliani and ask him why he would make such a decision with his former experiance of being a lawyer and knowing how important evidence in a crime scene is....lemme know what he says...
