Its really easy to point a finger and find fault.
On the other hand, it was 2 young guys having what they thought was a good time - and their fun turned into a tragedy.
Many of us here have made poor choices and have been fortunate enough that there werent tragic consequences.
People all over the world make poor choices daily. Most of the time the consequences arent tragic.
Just be glad if you've never had a poor choice end up this way.
