Everything must blow your mind. This is like going to a hotel and asking to see a list of people who stayed in the hotel last week because the suspect is probably staying nearby. Sounds like a pretty good way to get leads without asking for too much info.
Figuring out who searched for the address where the crime happened actually just sounds like good police work
search warrant that required Google to provide the IP addresses of anyone who had searched for the address of a home within the previous 15 days of it being set on fire
I’m fine with this. It’s specific to an actual crime that happened, and not targeting a known individual or preventing something that hasn’t happened yet, “for the children” or some nonsense like that.
