According to lombroso's findings, which physical attribute may add to a person's inclination toward crimes?

Answer: a protruding forehead

I believe the answer is: hawk-like noses and bloodshot eyes

According to his view, hawk-like noses and bloodshot eyes are the characteristic that is held by all living organisms which had the tendencies to become violent. In humans, this characteristic tend to contribute to higher tendencies/inclinations in doing criminal behaviour.
