Can I sue a bad landlord?

The owner of the park I live in told one of his tenants who's been doing some work for that he saw me moving some things out of my house and that I was going to skip out on paying my rent. So he told him to come over and take my work tools out of my shed and put them in his shed and he did it. The kid that lives in the house behind mine saw him do it and came and told me. And a friend of mine who also lives in park was at my house when it happen and said he would go and talk to him. When he came back the guy was with him and told me that the owner said that I owed him rent and he wanted the tools. When the witness asked him why he was looking at his shed too, things turned bad fast. I asked him to leave my home and he refused to go. At that my son who was in his room heard all of it came carrying his gun and told him to leave now. That's when he said he had a gun on him. He then left while I was on the phone with the sheriff's. This whole thing put a lot of stress on my family. Can I sue the owner for all he put us through?
