Also, Mageau was blinded by a spotlight,how much could he have seen?
Mageau was blinded by the spotlight initially, before the Zodiac began firing. But Mike claims he saw the guy, IIRC, afterwards, as he lay on the ground.
And if for a second, Collins was telling the truth about Cecelia seeing glasses on Z before he put on the mask, then it's just one more incident of Z wearing glasses.
Cecelia said she saw glasses, the report goes, so he had glasses according to that narrative. Adding what Collins claims doesn't bump to the score 2 to 1 in Shepard favor. At best it remains 1 to 1. Cecelia is still just one witness, the only one at LB who claimed, allegedly, the Zodiac was wearing specs.
Lastly, the Stine witnesses, they saw Z wearing those glasses immediately, could they have been part of a disguise?
Immediately? They didn't see Stine arrive, nor did they see the Zodiac firing the gun. The kids came in after the action began, IIRC, which means they missed part of what happened, which might have included the Zodiac popping out of the backseat sans glasses.
All I know, is that Z wearing glasses is listed in multiple reports.
Yes, and if I scream "JFK was a Martian" off a mountainside, the resulting echo doesn't add increasing credibility to a falsehood.
