What utterly senseless destruction.

The place is in a society with freedom of speech, where individuals have the ability to build and create, to write, to produce, to entertain, to inform, to study, to research, to debate.

And then one afternoon a person hits the accelerator pedal on a car and mows down a crowd. 

Was it a narrow-minded and frustrated person with a firmly held ideology and a power-hungry motivation to push that ideology upon others? Was it a person seeking a vile form of fame and attention? Was it a person with a psychiatric illness? 

Those facts are not yet known. But what utterly senseless destruction. 

Education is our best tool. Aged three aged seven aged sixteen. A well and broadly educated society is the least likely to face violent mayhem.
