Yeah publicity on everything has changed society for sure..As far as casey anthony goes, the DA screwed up their case so badly that jack the ripper would've walked. But that's what happens when the DA bows to public pressure for a quick trial rather than taking time to properly vet everything. The same people screaming for her head are why she's a free woman.
Maybe its be pause of the 24 hour news cycles looking for something..
stuff on a lot of things gets into the public eye. But the press seems to pick and choose also.
