Let's not be too hard on the alcoholic driver I'm pretty sure there were 4 idiots who chose to get in that vehicle with him and regardless of not having safety devices chose to be passengers with a drunk driver. 

Here's a thought make every single person accountable for their actions.  Can't make the deceased accountable so manslaughter for the driver for sure.  But why is it passengers always get a free pass when choosing to ride with a drunk driver?  They were behaving stupidly to get in a vehicle that didn't have seats or safety belts to begin with.  Not to mention the driver had been consuming and most likely he had been consuming WITH them.  My sympathy meter is used up. 

My condolences to the family of the deceased but aside from that, this is the price you pay for acting like your life doesn't matter when you choose to put it in harms way.
