This situation is a bit different. First thing is that the preliminary hearing has to occur in which the judge will decide which charges will move forward in court of common please. The prosecution does not the victim to testify or cooperate if there are other witnesses. Even if there are not other witness, the DA could still subpoena the victim and compel her to tesify, although more times than not that does not occur. I am not going to address the issue of the children being potential witnesses.
More importantly, this case involves charges that involved the assault of the police officers other charges relating to the officers. I can assure you they will not back down and not show up. One officer has been well recognized for prior police related work in the line of duty.
I suggest anyone out there to share your thoughts and concerns with the DAs office as they represent the public and public feedback about your concerns and public safety will go into their decision about whether the prosecute. Be constructive and provide examples and proof, and it will be considered or possible used (not to determine guilt) but in the case to refute any positive spin his defense tries to make. If he attorney does that, it allows the prosecution the ability to present evidence to refute that.
