And yet if you hang an empty chair in your own yard you will get a visit by the Secret Service.
But if a union goon threatens a sitting Governor’s family?
Nobody cares...
As Governor of the State, he has at his disposal the Michigan Department public safety, the Michigan State Patrol or his own personal security detail to prevent any threats to his daughter from the Rev.
The governor of a state is a power in his own right. He has "resources"....he has access to organizations and individuals that he can use to ensure the safety of his family, his self, and the people of Michigan.
An implied threat against his children has been made. Lots of people heard it. I would assume that the Governor takes the threat very seriously. He knows who made the threat, where the person who made the threat works and most likely where he lives.
If the governor is a real man and a real governor, he will "reason" with the person who made this threat and convince the person that he should agree to STFU, or if not, be prosecuted for terrorism.
