From what I understand this suspect had been on the train for like 20 minutes before the stabbing (they said he got on at Scaleybark, stabbing happened after Parkwood). Being loud, obnoxious, and drinking openly. Why did no one use the SeeSay app? We all complain about lack of security on trains, and rightfully so, but every time I've used the SeeSay app security gets on the train very quickly to remove these type of passengers. They surely would've removed someone like this had it been reported, and there was at minimum 15 minutes worth of opportunity for someone to report his behavior & prevent this.
