I don't think we should have them at all. If the data is collected, then it can be abused.

So with warrants we're essentially saying, "the government can track everyone's location and we're okay with that but they can't legally look at it without a warrant". Good luck seeing consequences for breaking that when we can't even get consequences for shooting people.

Still better than no warrants, it would be great to get warrants requirement. But we should not live in such a surveilled society.

It's still mass surveillance. Even if it requires a warrant.

Surveillance should work like this: You suspect some of a crime? Then you surveil them and investigate them. you need more powerful tools, then you need to get a warrant from a judge to surveil them more.

We shouldn't be investigating and surveilling people that aren't suspected of crimes. Mass surveillance treats everyone like criminals.
