A jury has been picked in Cleveland in the hate crime trial involving more than a dozen members of an Ohio Amish splinter group.
They are charged in beard and hair-cutting attacks on other Amish people last year.
The 16 people are charged in three separate attacks on nine people.
The crimes hit the Amish community in Jefferson County, Ohio hard.
Federal prosecutors say the hair-cutting attacks were intended to humiliate the victims because a beard is a symbol of a man's identity among the Amish.
Prosecutors are alleging the attacks were revenge for a dispute between Samuel Mullet, Senior and other Amish bishops after those bishops argued against eight families from Mullet's breakaway group being excommunicated.
