The acquittal of Lemrick Nelson in the murder of Yankel Rosenbaum has brought to the surface much of the anger that the Jewish community has felt since the Crown Heights Riots. Somewhere in Crown Heights is a person who stabbed Mr. Rosenbaum to death. Jews are entitled to be upset that he walks the streets a free man. They are not, however, entitled to feel confident that his name is Lemrick Nelson. The community is entitled to be disappointed that the justice system has not yet succeeded in bringing the killer to justice. But not to accuse the Nelson jury of racial bias, or of betrayal of its oath.
