No, they don't. I worked for a large DA's office in CA for many years, and I never saw the likes of this in the jurisdiction in which I worked nor did I hear of or notice any in the other fifty-seven jurisdictions in the state. This case would be blown out at the prelim. The charges would not be sustained, and no DA in his right mind would have brought them in this situation. The photo arrays, the DNA dragnet, the prejudicial statements made by the DA, the identification - all would have been laughed out of court.
They still may be laughed out of court. I am pretty sure the defense attorneys are good and will be filing all sorts of motions. And weak cases go to trial all the time. I find it surprising that you have such a different view.
