This moment was likely one of the last straws, and put a target on Alex Jones back. From the 2016 Hillary campaign. Infowas had a contest where they would pay people to do this. It wasn't just a random fan. This was an official Infowars operation, which REALLY pissed off the Clinton Crime family.
Infowars will likely be shut down in the next few months, if you didn't hear. Alex will likely continue on in some capacity, on some platform, but the Infowars studio and website, and maybe even Alex Jones person Twitter account (which the lawyers are trying to take as well) is in its twilight.
