Ah yes, the mysterious goat tests, George.
IF they ever occurred (which I SINCERELY doubt, as no one can provide one credible shred of evidence that they did), what they they tell us?
That Glasers are extremely effective if you ever need to stop a drugged goat that is standing full broadside to you.
Other than that, these goat tests are absolutely and completely worthless for telling us anything about how bullets will behave in the human body.
Hate to tell you all this, but a goat's anatomy isn't much like a human's anatomy.
