As a follow up I want to let all of you who took the time to post that I had discussions, this morning, with the other residents that he confronted and we went to management with it. Although the manager took a your- inconveniencing- me- this- early- in- the- morning attitude we did get her to agree to call his daughter- in- law and APS. I'm following up with a letter and there is a possibility that his daughter in law is a Novato sheriff.
Thanks again to everyone for taking the time to post experience and advice you may very well have helped prevent a potential tragedy.
