I’m not sure if I can provide an answer good enough since I never got involved in social work circles, but I’ll do my best.
Since, I imagine, they work with cases involving children being molested among other things, they may benefit from knowing many (little over 50%, if I recall correctly) child molesters are not pedophiles and may need a different approach based on whatever led them this way. For example, it would be ineffective to apply a prevention program designed for pedophiles to a person who abused a child due to hypersexuality and kids just being easier to take advantage of, and so on.
Same realization can help in noticing more types of behaviors as risk factors.
Also, most pedophiles are extremely hard to spot: we are not staring at kids and licking our lips or something :D We are not all men in our 40’s (in fact, pedophilic thoughts normally arise first during puberty and then last a lifetime), we don’t all wear round glasses and a moustache. In fact, for the most part, there is no need to identify us in the first place since most of us are entirely harmless. And yes, some of the social workers, teachers etc. will undoubtedly be pedophiles, most without any malicious intent.
That’s all I can think of off the back of my head that can be useful. Feel free to ask further questions!
Thanks for being compassionate and understanding :)
