Okay, that link you gave:
http://www.outsidethebeltway.com/google-searches-for-pressure-cooker-and-backpacks-lead-to-fbi-visit/
It links to the following for the article:
https://medium.com/something-like-falling/2e7d13e54724
Unfortunately, THAT link actually gets you this:
And what is medium.com anyway?
So you basically linked to a fiction posting site to claim something about backpacks, pressure cookers, and prism?

Medium is a new place on the Internet where people share ideas and stories that are longer than 140 characters and not just for friends. It’s designed for little stories that make your day better and manifestos that change the world. It’s used by everyone from professional journalists to amateur cooks. It’s simple, beautiful, collaborative, and it helps you find the right audience for whatever you have to say.
