Mangione, 26, didn’t speak at the hearing. Judge Gregory Carro ordered him to remain handcuffed, calling it a security measure. Mangione’s lawyer, Karen Friedman Agnifilo, argued that the sight of Mangione in shackles in the closely watched case was robbing him of his presumption of innocence.

Mangione's supporters started lining up outside the courthouse around 4 a.m., hoping to get a seat for his afternoon pre-trial hearing.
