Legal cases and courtroom arguments increasingly feature evidence culled from mobile and smart devices. That trend will surely increase since multiple devices are likely collecting data about you at any given moment.A recent case in point: A woman in Pennsylvania reported a break-in and told police she was awoken from sleeping by the intruder. Coupled with a lack of physical evidence outside the home, the woman's Fitbit showed that she was up walking around throughout the entire night. She ended up being charged with filing a false police report.There are additional reports of Fitbit's helping to convict a husband of murder, and recordings from Amazon Echo used as legal evidence (Amazon released the data for the case only after the defendant gave the okay).The bottom line: Many people have some type of device tracking their every movement, whether it's their phone, a fitness tracker, or a smart watch. Additionally, with the ease of use and abundance of home security cameras, digital doorbells and smart home assistants like Echo and Google Home, it is getting increasingly difficult to hide any types of crimes from being recorded by something.
