No, they would know by comparing the facts alleged in the report to the law, just like, when those facts were confirmed by the investigation, they compared those same facts to the law.

Now, I am not saying that a report which on its face does not describe a violation does not warrant investigation, but absent some other evidence which provides cause to believe a violation exists which would legally impact parental suitability, it doesn’t warrant limiting parental rights during the investigation, just as a report to police that raises articulable suspicion but not probable cause to believe a specific crime has occurred warrants investigation, but not arrest.

Are these guys Inspector Clouseau? 2 weeks of investigation to determine whether kid was abused by walking home. Legends. They must have been chasing down leads. Stake outs at the house. Subpoena the teachers.

Hahaha. Government employees lol.
