Read a stat. somewhere that there are 500,000+++ killed by traffic accidents every year in North America. The majority are males between 18-25 years old. Speeding, Alcohol are the main culprits.
Unfortunately Snyder and Heatley (although he wasn't drunk, he was speeding) are just one person/accident that contributes to that statistic. He was 1 killed in 500,000. As cold as that may seem, they are famous and thus the accident is isolated and the tragedy is focused that much more.
Everyone speeds and accidents happens. Sometimes it's your fault, sometimes its the other persons fault. You could be driving a Lada or a Porsche and the results could be the same. That's life I guess, eh?
