Full Disclosure: Re: Encrypted files and the 5th amendment

Yeah, I'm sure there are ways to draw as little attention as possible, but I also agree with you that in the scope of 
the investigation, it's not going to take a genius to see that there is something wrong about available size...  
However, evidence by exclusion is not admissible.  

But again, the "I forgot" defense is very hard to prove against as well.  What we don't want is a path to where NOT 
providing unencrypted data is a crime in itself, because all that becomes is a method to ensure that you get prosecuted 
for *something* irrespective of what can be proved.  

I have a bad feeling about this stuff.
