I would agree to a point if it were the first time they met. They were friends, had done this before, and both knew exactly what was going on...in my opinion.
The bottom line is that two guys are dead and their families are hurt and want someone to blame. I've been there and I understand what they're going through. It sucks. But, the healing won't begin until they realize the culpability of their loved ones in their own demise.
