The situation about Lori Drew & Ashley Grills.?

I have a very, interesting question that I'm sure that ANY of you can answer about this whole situation, but, why in the world didn't they just marched their s onto Tina's doorstep, & just simply asked her neighbor if Megan was bullying Sarah so that they can have the situation resolved within themselves? Now how hard is that? It’s not. This whole tragedy could have all been avoided if they were to simply do that of what I said. Selfish. Plus just because Lori or Ashley (or Tina) didn't exactly cause Megan to commit suicide, doesn't mean that they'll (Lori & Ashley) get any free pes from me, because they started this whole situation in the first place. The only sympathy that I have is Megan's parents, because they did the best that they could of the situation. But nobody can make someone commit suicide, though.
