Im sorry your husband isn't the type to just take the reins , my first husband was that way also.
I understand what your saying about the law, it really is slanted towards enabling the bad ones..
As for moving.. I agree about hiring some movers , if you cant afford to hire actual " moving people" you can check if you area has a " day labor" office, People can be hired from there for the day, Or if your near a college , College guys always need some xtra party money, even check with a local church many times they have members that are always looking to earn some xtra money......
I do agree that you need people around on the day you are actually moving. The fact that he has weapons is a issue for sure. Maybe just asking the police what you should do if he does start a rukus on moving day could help settle some of your fears , the unknowns are really hard for me to manage.
Stay safe and do what you need to
