When I was 18 and 19, I rode the Greyhound bus all over North America - to every corner of Canada, the USA, and Mexico. I spent a total of six months touring these countries, and while I can agree that Greyhound does cater to the "interesting" realm of society and the co-riders aren't always the most normal people you could encounter, I never really had any problems with crime, or in this case, murder.
I was planning a trip to Florida soon, thinking of riding Greyhound down (a 30 hour drive), but I think I'll take a plane, instead.
Canada's CTV news broke a story today about a Greyhound bus travelling to Winnipeg, Manitoba (the same bus which I've rode countless (at least 40) times in my life) on which a murder took place. In the middle of the night, one teenager attacked another (who was sleeping), repeatedly stabbing him in the neck and then decapitating him.
I have not heard a story this morose and depressing in a long time. This level of psychosis is something usually only seen in movies. To think I could have easily been a passenger on this bus and witnessed this is beyond belief. The attack does appear to be targeted, though (the attacker let everyone off of the bus without harming them, so I'm assuming this was to settle a score).

I'd expect (well, I'd strongly hope) that Greyhound will re-work its security (it has none) and have passengers go through X-Ray and metal detection devices before boarding. If buses were treated the same as planes, an attack like this would have been impossible.
Just my two cents, but I do think the bus is one of the most unsafe forms of travel.
