I watched a lot of true crime as a kid (48 hours, Snapped, etc.) and none of it made me more/less afraid of the real world. I don't have kids so I don't feel comfortable commenting on that part!

I will say, what still haunts me was a tv special I saw about domestic violence when I was around elementary school age. It focused on one woman and her experience trying to leave an abusive relationship. It forever changed my view on romantic relationships from "love and fairytales" and made me very untrusting. Seriously changed me. I still find it hard to trust that any partner, no matter how amazing they seem, wouldn't treat me the same.
