Libel and defamation are forms of disinformation and have long been held to have civil repercussions. This case against Alex Jones is an extension of that IMHO.
I have yet to see what tangible damages Alex Jones caused the parents of the Sandy Hook incident. Emotional damages to be sure, but I don't believe fining someone because they hurt another's feelings is a good precedent to set.
Other parents were compelled to hire full time security[2], which can't be cheap.
