BERMAN: In Baltimore, any minute now, we're expecting two rulings in a critical pretrial hearing in the Freddie Gray case. This, as police are on alert for potential unrest today. This morning will have been protests on the streets. Some chanting "Justice now." Earlier, there was been one arrest. Activists are planning demonstrations throughout the day. Freddie Gray died in April after suffering a spinal injury while being transported inside a police van. Six officers now facing charges ranging from murder to manslaughter. All have pleaded not guilty at this point. But again, a crucial pretrial hearing. The judge could all but throw out the case, or certainly say the prosecutor can no longer try it. For the latest, I'm joined by CNN's Jean Casarez live outside the courthouse in Baltimore -- Jean?</s>JEAN CASAREZ, CNN CORRESPONDENT: A crucial decisions being made in that courtroom. And the anticipation is building, John, because I'm hearing some helicopters overhead. People know it's an important day today. And here's what we do know. There was a break a short time ago, and we heard that the judge was expected to announce decisions on two critical motions.
