Seriously, chiefsfootballfan, that indicates Martin was on top and putting the beat down easily on Zimmerman because he was stronger and in better shape. It could have been a very short period with just a few blows and Zimmerman didn't have a chance. Just a possibility.
“Experience should teach us to be most on our guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.” — James Madison
