You should get one of those dictaphones and record any suspect conversations, it works on judge judy
so if he ever calls up to abuse you just hit record and listen to his abuse trying to make yourself sound frightened but not irrational this helps them throw the book at him quite a bit harder.
I'm pretty sure you will be able to borrow one from one of your lawyers they always have one and if you get Mike better then they get more so they like it
(see page 384 - money hungry lawyers concept)
