As details have come out over time it appears this guy (the professor) is a bit of a jerk , evidently he is a teacher at Tufts university near Boston Massachusetts , as such he is not FOB (Fresh Of the Boat)and has spent some time in the US and as such knows the laws about crossing the street ,

As I said in an earlier post he is probably just an effette intellectual looking for a bit of rough and wanted to get slapped around
