Little did you suspect that the purchases you made would trigger a red flag in certain government databases, but you should have.
They come while you are resting after the long, hard work of the previous morning. The door busts off the hinges a little too easily, and you get tasered more times than you can keep count. Your accumulators are confiscated, your phone, your computer, your papers: nothing is exempt, and soon they are taking things like your clothes and new sofa out of the house.
There is allegedly a warrant you can read, but you are too sore from when your face was kicked in for resisting arrest to do anything but sob. You certainly didn't know a warrant made it legal for them to just burn all your things on the front lawn.
