People focus on the glovebox DNA, but the points brought up in the civil suit also cover all the unknown DNA in the bedroom, bike, helmet, back seat of Suzanne's car. as well as the glovebox .. and when they received the information from prosecution... could be anybody's DNA in all those locations, but I think the civil lawyers have a different argument than whose DNA was on the glovebox.
Putting aside the wild ideas about a conspiracy against Barry, as far as I can tell, broadly speaking, the plaintiffs only really make out two potential complaints.
1. Persistent Discovery violations
The problem with this complaint is the conduct 99% relates to the period post prelim and pre-trial, and BM already had his remedy here. He was also not in jail during this time, and an actual Judge found the case strong enough to go to trial. I suspect it would be very difficult to convince another court as a legal question, that it can go to a jury to second guess the judge. In other words, the run up to trial was at all times subject to judicial oversight and a judge was at all times happy there was a case to answer even post sanctions. Notably, Judge Lama did not agree to dismiss the charges when he implemented sanctions, despite full knowledge of the discovery issues
2. DNA/Alternate suspect
Despite the issues at the prelim with Cahill (again subject to judicial oversight) at no time were the prosecution aware of an alternate suspect via DNA. The fact that there is unidentified DNA in a house or in a car is not a constitutional violation
There seems to be two consistent themes in the pleading which strike me as misguided
First that the AA should contain exculpatory evidence. But no AAs i have seen include the defence case. They include the evidence that is incriminating. And second that law enforcement cannot be tricky or bluff the defendant in interrogation. But that is incorrect. The defendant has the protections of the constitution in not having to answer. But if he goes ahead and makes damaging admissions that is his problem. There is no suggestion that law enforcement used improper pressures etc.
So yeah - my 02c but this strikes me more as posturing than a real law suit they intend to bring to trial.
Especially the use of repetitive paras "ZOMG Grusing showed a pin map of lies and deceit" strikes me as written for a lay audience more than a court
