IIRC, one of the critical things that caused the Sandy Hook families to get such a high payout from the Alex Jones/Infowars suit was the tearful testimony of one of the Sandy Hook victims, who was injured in the shooting, explaining to the jury that their own father accused them of lying and being a “crisis actor” because of Infowars bullshit conspiracy misinformation.

So yeah, it works. Shockingly well, even in situations where people have every reason to know better.
