My best knowledge:
east lot - PSP trooper, Collins, Tedeski, Kuss
west lot - Vensel, Sasse, at least two undercover cops
The troopers dashcam video was not released. The congressional Task Force showed some part of it, without sound.
Vensel’s bodycam was activated only later. By the way, he should be asked about the window the rallygoer witness talked about. (Someone was looking out of the window. But which one?)
Blasko arrived only after the shots. (His testimony should be clarified. He grabbed his rifle when arrived, just before the shots rang out. But he must have heard Collins reported on radio about the long gun.)
