That, or ignores the perfectly functional gun laying beside the bad guy, leaving it for him to pick it back up when he resumes pursuit.
I knew a girl who went to one of those "self defense" courses. The instructor told her to hose down an attacker with pepper spray and then run.
ASSUMING the thing works at all, and ASSUMING you get them in the face before they get a hand up, and ASSUMING they're actually somewhat incapacitated instead of thrown into a flaming rage, I figured it would be an opportune time to work the guy over with the proverbial blunt instrument, or tapdance on his crotch with spike heels, or at least kick him really hard a few times. But no, they're supposed to run. Screeching and waving their arms, I assume.
I guess it's a guy thing. If you take down your attacker it's not time to flee, it's time for revenge...
