Times are changing, nowadays you can commit crimes without even going out of your house, real-time encrypted communication with your whole gang.
When has this not been true? Invite a bunch of neighbours over with some balloons tied to the front porch, and a sign up that says "Happy Birthday Son!"
Then, sit in the kitchen talking about your plans to blow up some local municipal building, while some co-conspirator dresses as a clown and entertains the kiddies in the front room that you can see through the window from the street. (Ok, so you probably had to leave the house to buy the balloons, but still.)
Police methods and laws need to keep up with the technology and their use by criminals.
Provide evidence to a judge, receive a warrant. That's the process. Period. As technology progresses, the types of evidence you can present to a judge also progress. That right there is now they keep up with the technology.
