"The 13-year-old student who claimed that her teacher showed Muslim students a naked depiction of the prophet Muhammad has admitted that she was lying. This lie led to the beheading of that teacher."
"Her father has now been arrested for "complicity in a terrorist killing." Prosecutors say that the father's actions had a direct "casual link" to the teacher's death.
The 13-year-old faces slander charges."
Charges are probably justified here, for both of them.
From a *strategic* point of view, suspended sentences are probably correct for the daughter and even father. Depends on how exactly she wound up admitted to lying about it. You want to ensure people are willing to come forward and admit the truth.
