(The first time he awakened the pilot, he did so by tapping the
co-pilot on the shoulder. The co-pilot looked over, saw the captain
sleeping, and began "screaming" at him, according to the report. I
doubt an American first officer would scream at his captain.)

No, you're right there. Several times, on both sides of the pedastal, I
woke the other guy by simply calling his name.

Nor would a Japanese F/O scream, in the absence of the check pilot. But
since they had been caught, the F/O had to make himself look bad (for his
failure in "allowing" the Cpt to doze off) by the rude and crude yelling.
Absent the check pilot, more subtlety would have been in order. Have the
F/A slam the cockpit door, perhaps, then apologize profusely for her
clumsiness.
