Your digital Assistant can testify against you in court. Worth using?

Welcome to the new digital world, when the devices that surround us can become star witnesses in our prosecution. Data from fitness trackers has called BS on multiple suspects' alibis. And police included recordings from the always-listening digital assistant in an investigation of at least one murder case.

One case is Richard Dabate was found bleeding, his with zip ties. It was two days before Christmas in 2015, and a trail of blood led to the basement of Dabate's home just outside Hartford, Connecticut.
Dabate told police a masked intruder had killed his wife, Connie, and tortured him. With no witnesses and no suspects, police turned to a smorgasbord of digital devices for clues, from the house's to phone records, Facebook posts and a digital key fob.
But Connie Dabate's was perhaps the best witness of all.
Its data showed she'd walked 1,217 feet after getting home from exercise class — far more than the 125 feet in Richard's scenario, when he told police she'd run straight to the basement from the garage. The Fitbit also revealed Connie had wandered around the house until nearly 10 a.m., yet Richard had said she was killed about an hour earlier.
Dabate is free on $1 million bail . according to cnet

Well, these digital assistants can be of great help and maybe in the days to come can be of great disadvantages.
If you have one, they're listening. Will they be called to a witness stand one day?
