He summarized in Slate:
We tend to think that high-speed chases are a problem because of the dangers they pose during the chase. That's true enough. But the real problem is the danger they pose after the chase. I cannot tell you how many cops I talked to who spoke of how disoriented and crazed and incoherent they were after racing after someone through streets at 120 miles per hour. You finally cut off the suspect's car. You charge out of the cruiser. You yank open his door. Your pulse is 175. Your heart is in your throat. Your body is awash in adrenalin and cortisol. And everything we know about human physiology and psychology says that no one can make intelligent snap decisions under those circumstances.
Today the police said the man was unconnected to the attacks.
