Unless something has changed (or I'm simply clueless), it's not quite so trivial to ask where my phone was on January 30th. Camera surveillance is not time-limited.

It’s quite common for cell phone carriers to provide law enforcement with historical records of which towers a phone was connected to at specific times. Also the phone itself stores detailed location history, including which wifi networks it connected to, allowing police to get someone’s movements if their phone is seized as evidence. Police can even use battery temperature history to get an idea of whether the phone was on someone’s body, outside in the heat/cold, etc.
None of that sounds as straightforward as a dragnet would be. Most require a target to be identified.
