She googled "pressure cookers", he googled "backpacks". Weeks later the police showed up and interrogated him and searched their house for 45 minutes, without a warrant:
"45 minutes later, they shook my husband’s hand and left. That’s when he called me and relayed the story. That’s when I felt a sense of creeping dread take over. What else had I looked up? What kind of searches did I do that alone seemed innocent enough but put together could make someone suspicious? Were they judging me because my house was a mess (Oh my god, the joint terrorism task force was in my house and there were dirty dishes in my sink!). Mostly I felt a great sense of anxiety. This is where we are at. Where you have no expectation of privacy. Where trying to learn how to cook some lentils could possibly land you on a watch list. Where you have to watch every little thing you do because someone else is watching every little thing you do."
I wonder what happens when you don't agree to let them search your house? Face down on the floor in handcuffs? The m/o of the tyranny is to intimidate you into relinquishing your rights. The Redcoats aren't coming. They're already here.
