That's probably true, but it's not a certainty. In the mean time Karen Read is being defended as she should be.
In this case I feel that the defense in trial x1 did what they could to point to other possible suspects. Maybe it was a strategic mistake, idk, but the suspect phone activity of B. Albert, J McCabe and B. Higgins and conflicting, discredible testimony, when combined with the lack of evidence JOK was hit by a vehicle, mean that the defense's approach in this particular case is valid imo rather than a generic playbook conspiratorial approach.
Then you had Proctor intent on pinning KR for his own misogynistic reasons and incompetent to boot. Probably messing with evidence (tail light, missing video, inverted video, lost video of every camera that could have shown the state of the tail light between 12.30am and when KR arrived back at JOk's house). Proctor likely messed with this stuff independent of knowing anything about others' ( Albert/ Higgins) possible involvement. Jmo.
The above is why I have a problem with using a broad conspiricist brush to characterise the defense in this case. I don't think it's called for. The possibility of others' involvement is not baseless. Jmo.
