I think most of this kind of thing can be attributed to adrenaline and the fog of war. The cop having 2 people in the prone position could very likely have apprehended a couple of teachers trying to leave the school. In stressful situations what people recall afterwords is rarely accurate.
The guy in the woods could have simply been going for a hike and cops will detain anyone in the area just to be safe because they don't know what is really happening in a situation like that.
A great architect is not made by way of a brain nearly so much as he is made by way of a cultivated, enriched heart.
