NYPD Officer indicted for manslaughter of unarmed suspect

As you may already know, a target/suspect has no right to be notified that he/she is the subject of a grand jury investigation.  They also have no right to be present or present testimony.  However, in many jurisdictions, including NYC, police officers under investigation for alleged excessive force are allowed to testify.  This arguably is one of the reasons that there are so few indictments. If the officer can present, or make up, something justifying the use of force, grand jurors will often believe them.  This is especially the case if the Prosecutor running the grand jury doesn't want an indictment.  If this case, the officer, who claimed his handgun discharged accidentally, did not testify and was indicted.  In this case, the officer who claimed that his gun went off unintentionally didn't testify. He was indicted for manslaughter.
