Spanking your child?

So I live on an army base and was informed today that an incident from September was reported to the FAP on post. They said it got reported that I spanked my 4 year old son at the playground. I can’t even recall this incident because it was probably something so minor. I talked to CID about the situation and they interviewed me for a bout 15 minutes and pretty much just asked basic questions about how me and my wife go about discipling our kids and how often. When we do we rarely spank them unless it’s something serious, and even then it’s just a quick pat on the butt to get their attention. After the investigation I wasn’t told really anything else but that they will just let my command know what the outcome is. Talking to the FAP counselor she just said she watched the interview and didn’t see anything out of the ordinary and explained she also has boys and ways to go about disciplining your kids. This is the first time I have ever gotten in trouble and dealt with anything like this. I talked to members of my command and they said they are not worried since they all know me and my kids so well. They come around the command a lot. My family is really close oriented so this has just completely ruined my day and all I can do is just hold my kids close. Never in a million years would I have thought I would be dealing with this over a spanking from 4 months ago.

** wanted to give an update to this! The social worker called me two weeks ago and said the case was dropped and never went to the board.**
