But, wouldn't implants be better?

In the same spirit as the last post, I somewhat support the system described in "In Texas, 28,000 Students Test an Electronic Eye":

In front of her gated apartment complex, Courtney Payne, a 9-year-old fourth grader with dark hair pulled tightly into a ponytail, exits a yellow school bus. Moments later, her movement is observed by Alan Bragg, the local police chief, standing in a windowless control room more than a mile away.

Chief Bragg is not using video surveillance. Rather, he watches an icon on a computer screen. The icon marks the spot on a map where Courtney got off the bus, and, on a larger level, it represents the latest in the convergence of technology and student security.

Hoping to prevent the loss of a child through kidnapping or more innocent circumstances, a few schools have begun monitoring student arrivals and departures using technology similar to that used to track livestock and pallets of retail shipments.

Here in a growing middle- and working-class suburb just north of Houston, the effort is undergoing its most ambitious test. The Spring Independent School District is equipping 28,000 students with ID badges containing computer chips that are read when the students get on and off school buses. The information is fed automatically by wireless phone to the police and school administrators...

To me, this sounds like a great idea with a poor current implementation. After all, badges can be removed or lost. They could be placed on household pets or even accomplices. Children could trade badges or drop them down a sewer.

What's obviously need here for the utmost in security are implanted chips. And, not to be morbid, several implants should be made in various random and undetectable parts of the body.

For the utmost in safety and security, everyone - not just impressionable children - should go and Get Chipped [TM].
