"An ugly pattern is emerging in New York. This was a massacre, this was not a shootout. And the U.S. attorney general must give America the assurance that we all have equal protection under the law. This is a travesty of justice today, but it is a pattern that deserves attention." the Rev. Jesse Jackson, speaking from Chicago.

AP Three detectives were acquitted of all charges Friday in the 50-shot killing of an unarmed groom-to-be on his wedding day, a case that put the NYPD at the center of another dispute involving allegations of excessive firepower.

Justice Arthur Cooperman delivered the verdict in a Queens courtroom packed with spectators, including victim Sean Bell's fiancee and parents, as at least 200 people gathered outside the building.

Shouts of "No! No! No!" and swearing erupted outside the courthouse immediately after the judge read his verdict, followed by cries of "Not guilty!," from within a huge crowd of people gathered outside the Queens courthouse. Some women were heard weeping loudly. Later, shouts of "Murderer! Murderer!" were heard. Bell, a 23-year-old black man, was killed in a hail of gunfire outside a seedy strip club in Queens on Nov. 25, 2006 — his wedding day — as he was leaving his bachelor party with two friends.

The officers, complaining that pretrial publicity had unfairly painted them as cold-blooded killers, opted to have the judge decide the case rather than a jury.

Officers Michael Oliver, 36, and Gescard Isnora, 29, stood trial for manslaughter while Officer Marc Cooper, 40, was charged only with reckless endangerment. Two other shooters weren't charged. Oliver squeezed off 31 shots; Isnora fired 11 rounds; and Cooper shot four times.

A conviction on manslaughter could have brought up to 25 years in prison; the penalty for reckless endangerment, a misdemeanor, is a year behind bars.

The case brought back painful memories of other NYPD shootings, such as the 1999 shooting of Amadou Diallo — an African immigrant who was gunned down in a hail of 41 bullets by police officers who mistook his wallet for a gun. The acquittal of the officers in that case created a storm of protest, with hundreds arrested after taking to the streets in demonstration.

The mood surrounding this case has been muted by comparison, although Bell's fiancee, parents and their supporters, including the Rev. Al Sharpton, have held rallies demanding that the officers — two of whom are black — be held accountable. [MORE]
