drive-by

Of a crime, etc.: carried out from a moving vehicle.

Done in a cursory or superficial manner with little regard for the issues involved; careless, offhand.

If the highly visible mockery of teenagers leads to a serious examination of the practices and institutions that perpetuate racism, perhaps it will be worth it. But I have my doubts. This kind of drive-by scapegoating does not seem conducive to genuine reflection (and it definitely doesn't encourage reflection in the individuals it scapegoats). It allows us to point the finger at other, younger, relatively powerless people, rather than consider the ways in which we're implicated in a problem that is much, much larger than a few misguided teenagers on Twitter.

But what hinders students far more than the technical side is Wikipedia's editing culture. Many of their contributions got reversed almost immediately, in what is known as a "drive-by deletion."

A crime, such as a shooting, carried out from a moving vehicle.
