Actually, 2.4 seconds is a long time. I think any moderately intelligent individual can readily process the situational information in that time and arrive at a reasoned response. Based on the available data, that is exactly what the marshall did. You are of course correct in excluding debate and committees, I wonder what effect the stress of the encounter & adrenalin dump might have on the processing. It looks like the feeding frenzy has begun. Reports on the radio this morning are questioning whether the guy said anything about having a bomb, and some of his freinds and family are claiming no knowledge of him being diagnosed with mental illness. I do hope the truth comes out, without media bias or political overtones.
