The murder trial of Baltimore police officer Gahiji Tshamba, who unloaded his service weapon into a former Marine outside a Baltimore bar last year, began Tuesday morning with hearings to determine what evidence can be presented in court, The Sun's Tricia Bishop reports.

Lawyers for Tshamba, 37, claim their client shot Tyrone Brown a dozen times in self-defense and was following proper police procedure during the incident, which happened in the early morning hours of June 5, 2010, after a night of club hopping. But prosecutors say Tshamba was intoxicated, irrational and that he murdered an innocent man who served the country.

The two sides spent the morning arguing about what can be said to a jury or judge, dependent upon what kind of trial Tshamba elects, though they agreed on one thing: Each wants the fact-finders to take a field trip to the crime scene, outside a back entrance to Club Hippo in Mount Vernon, during the proceeding.

"You don't get the largess of the situation until you get to the crime scene," said Assistant State's Attorney Kevin Wiggins.

Wiggins said at least two officers are prepared to testify that Tshamba appeared to be under the influence of alcohol after the shooting, talking about "how hot the chicks were that were with him that night" while he was being transported to Mercy Medical Center.
