That's the whole premise of automation and drag net though, no? Sure, it is absolutely legal for a private investigator to park their car outside my home and follow me as soon as I leave and go anywhere in public. They can write down this information and keep logs. However, should it be legal to automate this for everyone? I'm not asking whether it is legal but rather should it be.
