Totally random attacks like this are occurring all over the country on public transportation. We have reported on numerous cases around the country.

This took place on a Portland MAX platform. A black male walked to a group of young women and began either stabbing or slashing one. Video from a witness shows blood on the ground and a large straight razor.

Related: Last month an elderly white male was seriously injured and disfigured in a Portland suburb. He was eating at a Denny’s when a black male walked up to him, poured gasoline on his head and body and set him on fire. It was a totally random attack by a perp who already had a serious criminal record.
