I appreciate the rest of the details you've provided on the thread!
No, nonreporting is not. Active concealment/assistance is, and you just quoted a long bit of statute that says exactly that.
Nonreporting, whether or not one believes it is immoral, isn't the same thing as assistance in evading arrest. The government can conscript citizens into active assistance in enforcing the law, but issuing a warrant doesn't do that.
Nonreporting is legal, assistance is a crime (“accessory after the fact” is the general term.)
