Which brings me back around to the Feb. 2010 incident. I am fully aware that there is a log of all calls coming in, that includes at least the date, time, address, at least one party involved, and type of call. I am also quite sure that LE looked back as far as they were able to ascertain how many times they had been called to Billie's house. If there were no charges or report filed, then LE only has the small bit of info in the call log to go on.
So, it is very possible that all LE saw recently was "2/??/2010, 00:00?m, 1804 Chestnut, B.Dunn, domestic", or something to that effect. And, again, JMO, this is all LE has.
Now, in my mind (and JMO), LE questioned SA about this in their investigation of Hailey's disappearance. And he brought up (or admitted after being questioned more than once about this incident) that he threatened both Billie's and Hailey's lives. I think this for a couple of reasons - one being that this incident is wedged in between LE looking at SA's phone and then SA's defamation of Hailey's character. Also is the wording of this particular paragraph... it just could be interpreted more than one way. Another is because, as many people here have pointed out, he just seems to get a kick out of lying and misleading LE.
