There are laws against destroying evidence.
If you think the answer is to make it illegal to encrypt evidence too, well that’s one answer.
I think encryption should be available for all purposes except evading warrants.
The ‘neat’ thing about Iphones is one doesn’t have to destroy the evidence, the records are still there and ready to use or enjoy- a benefit matches and shredders can’t claim!
And any idiot can do it.
You’re as clueless as Cotton-head himself about the Constitutional and technical issues.
