Lucy McHugh murder suspect jailed for not revealing Facebook password

I don't entirely understand how these sort of cases pass the scrutiny of the 5th amendment. The founding fathers made it very clear that you cannot imprison people until they agree to admit their guilt, but that is precisely what we're doing now a days. You, as in the alleged offender, are not obligated to prove your innocence - it is the burden of the state to prove your guilt.

If we're so quick to ignore the spirit of laws previously passed then it undermines the value of the law itself. What relevance is there of decision made today, if they might simply be ignored tomorrow?
