Im sure surprised to see the quick response to a child abuse report in this case. When a friend called for help in a nearly identical situation, (dad choking and threatening younger sister) she was told someone would come out that night. They sat up all through the night, waiting. 

When no one showed up the big sis called DHS the next morning and was told "i don't  know why they told you someone would come out last night, we don't send anyone out unless a child is severely injured, has died, or is in foster care".  

Clearly child safety in Oregon is all about what county you live in.
