Or rather lack thereof.
It's law enforcement that's pushing so hard for these kill switches.
Right now I can walk into a T-Mobile store, buy an iPhone with cash, pay the first month with cash, and get a burner smartphone with a data plan. No ID, no name, no address, no credit check.
If this law is implemented, the ability to buy a smartphone anonymously goes away. You'll have to show an ID. For this law. How else will they know whether you're the person who can request that that phone be bricked?
This isn't about theft, the police don't give a shit about theft. If you don't believe that, try reporting one. This is about removing the anonymity of burner phones.
