What were the overall findings of the investigation, as reported in the video?

Failure to appropriately file required paperwork resulted in thousands of cases being reassigned.

Poor hiring practices led to CPS caseworkers ignoring the most serious cases due to a lack of concern.

CPS caseworkers might be able to use certain abuse risk factors to intervene more rapidly.

There was a pattern of CPS managers micromanaging follow$-$up rather than allowing caseworkers to do it$.$
