First of all, where in what you linked does it say that it was plainly visible to the naked eye?

And you obviously didn't read far enought:

Start HERE @ Line 14; be sure to see Page 14, specifically lines 1-7

I most certainly did read that testimony, and it is exactly as I represented. In fact, Mackey tries to say it wasn't enough blood to observe through the outside and he says it's "not very...", then goes on to say how the shirt was tucked in. That is exactly what I typed earlier in the thread. That he said Bryant had the shirt tucked in and he collected it without examining it and the lab saw it when they got it, and later he saw it for himself.

And nowhere does it say they had to use a microscope to see it. He says he when he did see the streaks on the shirt, when looking at the inside of the shirt you can, quote, "definitely see it".

No mention of needing a microscope at all.
