Do we really need to keep posting videos where people have probably died ? Its ghoulish imo. 
I'd tend to agree with that, despite the potential educational properties (which Al pointed out) 
I think it's worth being informed* of these things
for the educational value, and as a reminder that we're not wrapped in cotton wool.
* - Not necessarily seeing them in video, but if that's the only means by which they are presented...
As the registered keeper of an aircraft the CAA send me regular bulletins listing reports of every accident and incident that has been reported. I read all that are relevant to a glider pilot, and, once or twice, I've been doing something around the airfield or in the glider and thought "ahh.. someone came a cropper doing exactly this". It may be morbid to watch other people's mistakes, but each time a little information sinks in and makes you a little less likely to make the same mistake, IMHO.
Maybe the DVLA should do the same, although we'd probably all end up with a publication the size of a phone book to wade through each month.
