Well, the O-Theory has served as (a bit of a) trojan horse.
LE and NM have had to make some admissions on the record they might have not otherwise made had the Defense not chosen the O-Theory as SODDI argument.
For example, the State's had to explain why they've not included or have been unable to provide discovery timely, they've admitted that critical early investigation evidence has disappeared so it can't be provided, and they've had to address a line of investigation that was stopped before obvious phones were subpoenaed, and explain that geofencing of the crime scene may be minimal, incomplete, and/or not as robust as might be anticipated.
We'll have to be more patient to know what's on the record vs what will be presented at trial.
