Is it ethical for Baltimore's top prosecutor to keep trying for a conviction in the death of Freddie Gray? Legal experts say State's Attorney Marilyn Mosby should think hard before proceeding to trial against the four officers yet to be cleared.

Their fate will likely be decided by the same judge who said he's seen no evidence a crime was committed when Gray's neck was broken in the back of a police van.

The not-guilty verdict against van driver Caesar Goodson is more than just a setback for Mosby. Former state's attorney and mayor Kurt Schmoke says that if he still had Mosby's job, he would reevaluate the remaining cases and perhaps decide not to proceed.
