Yes, when I heard about this story I thought it stank of "trigger happy" policing.
Perhaps they were on edge after the shootings at the navy base, but still.. I don't think this was handled correctly at all, but since the media didn't kick up a fuss, we are preconditioned to just go along...
What I found terrible was that although the scene must have been pretty thoroughly examined, even the day after reports in the media still couldn't confirm whether there was even a child in the car.
If they had wanted us to feel emotional outrage, they would have played that angle more. Instead, it was all "unconfirmed reports" of a child (not a 1 year old baby as it turned out to be the case).
Anyway, the whole episode disgusts me, so I am outraged!
