There is no burden of proof and no consequence for perjury. 100% of the search or seizure warrants I have read have had obvious perjury in them.
I encrypt my data at rest not because I fear a burglar breaking in, but because I fear the FBI coming in the front door on some trumped up bullshit. Everyone has a right to privacy, even (and perhaps especially) if they are doing nothing wrong.
I’ve read too many stories of writers and activists getting bogus warrants and charges and arrests thrown at them to inconvenience and harass them to ever have a single unencrypted disk in my house.
