Hi there Krystal,
The decision was made for the following reason. You killed someone before posting PD raid while raiding the PD. The Damage logs show you initiated contact with the another person at the time. And you killed them before raiding the PD. That being said, the gentleman you have in the logs as a mug, stated it wasn't said to him. And it was a RDM. And of course due to the disconnection, there's really no way to get your side of the story. So as outlined in the D3A handbook, a 2 day ban for RDM + LTAP was given.

In that Imgur gallery you will find all pictures of the logs.
Best of luck.
