i asked bertie joe when we spoke. why do you do it?at's for me to know. >> they've had people willing to got extra mile to try to help them and in spite of everybody's attempts to try and show kindness and give them opportunity to start living differently, they continually come back to the same way of life. >> and it's been that way since the day we first met them. the hoaks twins scamming people and maybe fooling themselves, too. >> can you stay the course? can you do it? >> once i set my mind to do something, i can do it. it won't be easy, but then, nothing is.
