If your device is grabbed by the FBI from the Glen Park library, I don't think they'll be turning it off. Wouldn't they use some sort of device[0] to maintain the power supply? I assume they would also be aware a key fob was in use, at least if you were using reasonably well-known hardware like the ORWL.

I noticed the campaign details indicated the power supply voltage is monitored. Will this protect against a hot-plug?
