We would all need to be chipped.
At first, just the designated Bad Guys would need chipping. Then keyboards, like I mentioned, but after that detector portals sould scan these villians as they try to enter a school or public library, or a serial drunk driver entering a liquor store, or a felon at a gun store.
Eventually we'd all be chipped, but it will start with these special classes, pedophiles, drunk drivers, felons, Republicans...then eventually all of us.
It's just too convenient for statists to ignore.
