This case is extreme but, to be perfectly honest, in 16 years as a pediatric nurse I have seen DCF do too much twice (both cases involved children with undiagnosed osteogenesis imperfecta and unexplained fractures) and do too little too many times to count.

Someone in this case had to have filed a 51A against the parents otherwise DCF wouldn't have even known about it. It was a report of suspected abuse and was probably screened in as an emergency response, which led to the middle of the night response. If DCF hadn't removed these children and it actually was an abuse case, the outcome could have been deadly.
