As an ex special ed teacher and knowing what happens in regular ed, a lot goes on. Special ed kids sometimes come from special ed kids grown up and now parents and in reg. ed cases where things seemed fine but stuff was happening unseen. I've called child services with my principal and vice principal firmly behind me and the law saying as a teacher who suspects, I must. That made it easier, I was required by law and had support. But alone in a store, seeing things I didn't think should happen, I wasn't so brave. Out of control big parents were scary (I'm 5"1') and I had very little back-up. I knew what I saw but not any stories. By law, I had to call for a child in foster care and did, but knowing the story knew no good would come of my call and none did. But seeing another child and parent in crisis, intervention did help. Did what I could. That was the best I could do.
