1. They look at phones moving towards the crime scene and going dark when getting close. This is also how you can detect secret meetings between people. They move towards the same area and shut down their phones.

2. They look at suspect phone going dark anywhere around the time of the incident.

3. Leaving a phone at home that is not answering calls or creating traffic during the time of interest is also a lead (if you already have a suspect).

Google has announced that it is cutting off access to the Sync and "other Google Exclusive" APIs from all builds except Google Chrome. This will make the Fedora Chromium build significantly less functional (along with every other distro packaged Chromium)

Google sent me an email informing me that they will change the country associated with my account in 30 days. What I find curious is that it says the services are essentially the same between different countries. So, there is no advantage to me as a consumer for anything to change, the only difference will be in how my data is processed. Privacy alert! I found how to make a Country Association Inquiry to dispute this.
