I think that LE is very experienced at dealing with all the variety of human personalities, and many of them on the worst day of their lives following car accidents, shootings, etc. So I don't think SM's personality is a surprise to LE - they know what sort of character they are dealing with. LE is clear that they did not see GS on neighborhood cameras in support of SM's claim that he left the house on foot between 3:15-4:00pm Monday. Then LE specifically sought and were granted a SW for a Jetta car, which has been impounded... I think the volume right there is loud even though LE is publically silent. JMO
(The information re: Jetta impounded comes from SM's own words in her interview.)
Does anyone know what year for the Jetta and if it has manufacturer's GPS tracking?
