Just hide your phones and tell them to go F themselves.
Yep...and when they get warrant to sieze their phone, hand them over a burner phone.
RE: Hide your phones.
I guess you meant to address normal people.
I use what crime shows call a burner phone. Never owned a smartphone. Causes me trouble but I get over it.
To normal FReepers:
noun Informal. a disposable cell phone with prepaid service, often used with the intent to temporarily obscure the true identity or contact information of the user: Members of the cartel used burner phones to evade federal surveillance.
