Dear cupid,
You have several basis for a law suit and possibley criminal charges. You would need to find a local attorney to help you.
Here is what I see.
1. Intrusion or vioaltions of privacy: You can read more about this at: http://www.attorneytamrawilliams.com/article.jsp?practArea=20&articleIndex=3
2. Communicating a threat by having you taken out.
3. Assault and battery from the wife who grabbed your arm.
4. Your neigbor has the right to charge for trespass.
You should report the trespassing to the bank. They cannot do anything if you do not tell them and they do not know about it. They may or may not do anything, but they need to know about it. You may also have a lawsuit against the bank because they are not taking measures to protect the property from trespass and it is being used to conduct illegal activity...i.e. violations of privacy.
When you state that he said he did not know he was being intrusive or offensive, it makes it sound like he is acknowledging that now it is considered offensive, at least. If he continues to do the behavior it solidifies your right to file suit.
It is a decision you have to make. why don't you seek a restraining order against him and is spouse. this gives you protective orders, that if they violate it, they can go to jail and be fined.
The lawyer is not big deal. Simply go to the yellow pages and pick an attorney form a firm that has at least 2 or more attorneys and practice civil law. You only need about 20 minutes to know for sure if you have a strong case worth pursuing.
