I think it will be much rarer in the near future for the term to be used, if at all. Its not working in the age of social media. Once named as a POI someone's life is ruined.
Shannan's Watts parents have been constantly harassed and they are victims...
Her parents have hired attorney’s to try and stop the harassment. The harassment is nonstop, adding "we can't grieve." "We have been subject to threats on our lives all because we are victims of a painful tragedy," Rzucek said…..
Steven Lambert, the family's attorney, said they've contacted Facebook, Twitter and YouTube. Lambert said a group of people have been helping the family track down the cyber bullies and are "constantly reporting" them. But nothing has been done to stop the harassment.
"There's no regulatory arm of YouTube, there's no customer service line for YouTube, no customer service line for Facebook to contact," Lambert said. "And we have really tried and racked our brain over a year to get something done."
If this is how it goes for innocent grieving grandparents, imagine being a “person of interest”
Shannan's parent's have no one to sue, they are additional victims of Chris Watts but I would think a named POI who was innocent would be suing the police dept. in the near future.
