Let me help him out:
According to the NIH, the children of SUD parents are three times more likely than baseline to be sexually abused. Combined with Nick's own previous joking statements about children and his association with people like Melton and Vito, and the Kandiyohi County Sheriff's office apparent (but speculated collusion) to suppress matters of public concern for Nick, I am at least three times more concerned that Nick abuses his kids in such a manner than I am for the average father in America. Particularly because Nick Rekeita's daughter tested positive for cocaine metabolites and he has insisted that this test result is the product of a stranger (in this case law enforcement) somehow managing to dose her in a way that allowed a test to conclude she ingested a non-neglible amount of controlled substance.
Despite this, I make no assertion that he sexually abuses his kids. I'm just more concerned such a claim will manifest at some point against Nick than I am concerned it will manifest for the typical individual.
