If a right index finger print is found at a crime scene and the cops turn up a suspect, they don't try to get his right fingerprint and compare it. They try to get him printed. That means all the normal stuff. Each finger individually, all fingers in one box, etc.

I don't however think that a 'standard fingerprinting' involves inking the palm of the hand. Now if it does, then we really can't draw conclusions from it, but if I am correct that palms are not normally inked, then the fact that the cops obtained a palm print from some sort of 'suspect' is indeed significant.
