Wait and see, no leaping to conclusions, benefit of the doubt, yadda yadda yadda
Then the news continued, with reports that this same MO had been used to kill 3 French soldiers in the past week. I still thought the culprit was Muslim, but the PC spin was hard at work to weaken my resolve. The French soldiers were not only Muslims themselves, but black! As the day went on, the reports continued that the police were hunting for (drumroll) a neo-Nazi. It made sense: National Front type, they hate Jews, they hate blacks - why not?
Today the news reports that, what do you know? I was right all along: the shooter, currently holed up in an apartment with a bunch of guns, is named Mohammed Merah, generally described by his neighbors as a quiet man, with a penchant for watching “violent jihadist videos online, including footage of decapitations” at home.
The bad thing about knee-jerk reactions is that they so often turn out to be wrong and lead the one doing the jerking to do things that don't match the reality. When the jerking knee turns out to be right 95% of the time, we really have to come up with some other term for the reaction, one a little more in line with the the statistical likelihood.
UPDATE: "Mohammed Merah, a 23-year-old Frenchman of Algerian descent, ended a night’s silence when police closed in on him. Surveillance cameras show that he left a bathroom holding two firearms and shooting at the police, then jumped out a window while continuing to fire. He was found dead on the sidewalk below. It was not clear whether he was killed by the fall or by bullets."
As Captain Renault would have put it, "We are not sure if he committed suicide or died trying to escape..."
