I'm having a HUGE issue with the term "INCAPACITATED": let's apply some real life experience here
1. IF you've ever "run into a door" with almost any part of your body, you are often stunned, "befuddled", confused or just stopped your tracks for X minutes====incapacitated
2. IF you've ever "smashed your forehead" hard enough to cry out, you've probably been unable to "regroup" and stand, run & chase somebody === incapacitated
3. IF you've experienced any of the above & more scenarios or the misery of a TRUE (not JODI-ized) migraine you'd possibly experience nausea/or vomiting === incapacitated
SO......IF one takes the fantasy of the DT with the gunshot first, TRAVIS would be incapacitated by SOMETHING like above BUT definitely by the copious amounts of HIS BLOOD flowing from the highly vascular face/head(and adding insult to injury, the extraordinary pressure against ALL of his sinus cavities causing WICKED PAIN! & PRESSURE)
