That's not necessarily true.  Under federal law, if you are
deliberately ignorant of (that is, you take affirmative efforts to
avoid having knowledge of) some fact or condition, then you can be
held to have had "knowledge" of that fact or condition, and if that
leads to criminal liability, then so be it.

Also, in general, there are lots of things where you can be criminally
liable for things you didn't know about, if you were reckless with
respect to them.  The classic example is the act of throwing a rock
off a tall building.  You have no knowledge that this rock will hit
anyone (either in particular or generally), but you are reckless
towards the possibility that the rock will hit someone and are thus
criminally liable for the consequences if it does.

Should this change? I don't think there is any legal precedent for someone
who is not "aware" of criminal intent to be held culpable. 

I read a case in my criminal law class of a shop owner who was held
vicariously and criminally liable for the acts of a non-employee in
the shop without the shopowner's permission.  The law did not place
any requirement of culpability on the part of the shop owner (not even
negligence); liability was absolute.  However, the Supreme Court did
limit the scope of vicarious absolute liability offenses to strictly
financial penalties.  The Court has held that the Constitution
requires at least a threshhold level of individual culpability for
liability for an offense which can lead to incarceration.

IMO, it is Constitutionally permissible for a state to make it a
criminal offense for a person to operate a computer system in such a
manner that a substantial, avoidable risk exists that that computer
system may be used in the furtherance of illegal acts, especially if
the operator of the computer is or should have been aware of the
substantial risk.  Whether any existing law does so is another
question.
