I didn't assume that. I specifically pointed out that CPS has limited resources. Let's assume the process works in the moronic fashion you're suggesting. Texas CPS has under 10,000 people, of which about a third are investigators, and investigations typically take 2 weeks. Then there's the police/courts/jails that have their own limited resources.

Imagine how that'd work. If you called in a complaint about a ten-year old today, the kid would no longer be a minor by the time the investigation began. ;-)
