Alex Jones said multiple things about Sandy Hook on platforms including Reddit discussions:

• He claimed Sandy Hook was fake, saying it was a "synthetic" event with actors used, calling it a manufactured false flag operation to push gun control agendas. He accused parents of the victims of being actors and alleged some parents laughed before an interview, suggesting they were mocking the tragedy.

• Jones mocked a father of a Sandy Hook victim, using his nervous laughter as "proof" he was an actor, though previously had said people do weird things in grief. This was interpreted as him knowingly advancing a false narrative.

• He followed and harassed the families of the victims with this false claim, causing additional grief to them.

• In court trials over defamation claims by Sandy Hook families, Jones admitted it was reckless to say the killings did not happen, but he also changed his stories multiple times. He lost these suits and faced huge financial judgments.

• He has been described on Reddit as repeatedly lying in court about the Sandy Hook claims and showing blatant hypocrisy and disrespect to victims' families.

In summary, Jones portrayed Sandy Hook as a hoax with actors, harassed families, mocked victims, and lost defamation lawsuits related to those claims. These remarks and actions have been widely condemned on Reddit and beyond.
