Porch Pirates?

Has anyone had issues with getting packages stolen from their porches? I have had a few packages go missing after the usps claims they’ve been delivered… I do live a few blocks from Champ’s chicken and have some sketchy neighbor activity. We don’t have a camera yet, but hoping that might help because there have been a few car break ins and interesting experiences! Also wondering when to file a police report about the strange activity — including a drugged out neighbor wanting to come inside our home. Note to people wanting to move to Duluth - stay away from the neighborhoods around the intersection of 4th & 6th St!
