Earlier quoted context omitted.
They aren't independent actors because they were highly impressionable people whose actions were influenced by Jone's lies.
This is what the erosion of personal responsibility and accountability looks like. Alex Jones isnt responsible if stupid impressionable people watch his show and do stupid things. That is absurd and absolutely chilling in regards to free speech. Perhaps it even sets a new precedent that everyone who posts a comment/video/podcast online is now responsible for any illegal actions that any of their viewer commit.
No free speech is harmed here and the First Amendment protects you from the government silencing your speech.
