Instead of "criminal", I think you mean "intentionally engaged in an illegal enterprise". From the context, I doubt you mean to restrict the statement to those already convicted of crimes. Beyond that, it's very tough to know if you're currently committing any crimes (or any non-criminal illegal activity), as we don't even know how many laws we have.[0]
I agree that the vast majority of those that will have trouble are intentionally engaged in illegal activity. But, at any given time, there must be both fair fair number of people who are unintentionally committing illegal acts and those who are falsely believed by law enforcement to be committing illegal acts.
There is an argument to be made that everyone should be more careful about privacy, thereby increasing the cost (and opportunity cost) of invasive investigations and forcing law enforcement to be more selective about the degree of certainty they have before employing more invasive investigation techniques.
