AITA for plotting against my neighbor?

Let me start by saying that all of this happened today. I ordered a package, it was a $75 Walmart gift card. It was delivered today, but FedEx left it at the gate of my complex. I live in a gated community. After calling Walmart customer service and talking to them I go back outside to look for the package again. I then had the idea to text my landlord to see if he could run the cameras back to see who took my package. Guess what? It was my neighbor’s friend who took it. My landlord even sent the proof of her taking it. I then see her coming back with WALMART BAGS IN HAND! I confront her nicely, she denies it. I showed her and my neighbor the picture and she still denies it saying it was her package. About two weeks ago, this girl’s boyfriend was being violent and broke my neighbor’s window. This isn’t the first time they are said to steal something from the property, either. It has been nothing but drama since they moved in these apartments. Both me and my neighbor is on housing and is not supposed to have anyone living with us. My landlord told me to text my housing case manager because he wants to try to get the girl and her friend evicted. My landlord also said that if they do not leave, then my neighbor will also be evicted. I’m not mad at my neighbor as he didn’t do anything wrong; he just took up for his friend. If he is evicted, I just feel like he will be collateral damage and I honestly don’t want that. My landlord has made it clear that the only way that that will happen is if the people that he is allowing to live, there does not leave. AITA for plotting against my neighbor?
