For some ethicists and lawyers, however, releasing a sketch of a suspect without any witnesses seems like a dangerous proposition. Jay Stanley, a senior policy analyst at the American Civil Liberties Union, said that from what scientists have said and written, not enough is known about the link between genes and facial features to rely on the technology to produce a suspect.
You can lose weight, gain weight, change gender, grow a beard, have plastic surgery, Stanley said. It risks ensnaring innocent people in webs of suspicious investigations. It risks playing on existing societal racial prejudices. It risks diverting investigations down wild goose chases. If this technology were used to set up dragnets say to bring in every albino person in an area as a suspect because the DNA seemed to show someone had that trait, thats where we would object.
