KLTV has the story:
When 26-year-old Nathan Shafer heard about the arrests of 19 Occupy Columbia members outside the State House last Wednesday, he did what lots of people do when they get angry — he vented about it on the Internet. He saw Gov. Haley’s Facebook post about the arrests and Haley’s comment that she “appreciate[s] freedom of speech,” and that’s when authorities say Shafer crossed the line.
“I hope someone murders you before I do,” Shafer said he commented on the post. “How’s that for freedom of speech?”
The next day, Shafer says two State Law Enforcement Division agents visited him in Charlotte to discuss the comment.
Authorities later told him he would be prosecuted and he surrendered himself as you can see in the clip above. The story goes on to note that a similar threat against the President (also made online) was judged to be free speech and not a genuine threat.
