It's about when the hell did our gubmint officials feel they have the right to presume guilt before innocence?

However, governments can make and change "the rules" to their advantage whenever they want, and I'm sure they will. This is only a beginning - massive propaganda campaign ahead, I imagine - "Every bitcoiner eats three babies raw for breakfast, an IRS official told me, on condition of anonymity."
