OK - Beheading threat legit, or inopportune joking around?

In a bizarre coincidence, a fired Oklahoma City nursing home employee was arrested Friday after a co-worker reported he threatened to cut her head off.

Jacob Mugambi Muriithi, 30, is being held in the Oklahoma County jail on a terrorism complaint. His bail is set at $1 million.

Muriithi claims he and the co-worker were both joking around.

“It appears to be a case that the parties were mutually having a conversation and mutually joking,” defense attorney Christian Zeaman said.

“It sounds just like they were mutually having fun with each other. They were both joking. I think the (police) report really indicates that. ...I’m investigating this hot and heavy. ...He is a Catholic, he goes to church, he has the support of the community. It was never a terrorist hoax,” the attorney said.

Oklahoma’s anti-terrorism act specifically prohibits joking about an act of terrorism against a population.

Prosecutors allege Muriithi violated the act because he intended to cause “the population of Christians in Oklahoma County” and Garrett personally to experience a disruption of personal security, fear and anxiety.
