Does bullying happen more than we think?

In a disturbing video that's gone viral this week, a school bus monitor from upstate New York has become the Susan Boyle of bullying victims.

Karen Klein is a 68-year old grandmother who was verbally abused by seventh graders earlier this week. One of the kids recorded the ten-minute scene. The video ended up on YouTube, then a good Samaritan started a fundraising page for Karen Klein.

Today, they've raised nearly half a million dollars so Klein can retire in serenity. Meanwhile, the bullying kids and their parents are dealing with vigilante threats. Even NBC's Matt Lauer called the kids "monsters." Klein has been kinder to the young boys. She said they probably don't act that way at home and their parents might have no idea how terrible they behave.

Could that be true? Are parents aware of their children's character? Or are they in denial? Were the instigators in this case from troubled homes with disrespectful parents? When confronted with the facts, how do parents react?
