It is ridiculous but if we could have this done just for stopping kidnapping and other such stuff then I would be for it. However, it would have to be throughout the body somehow so, some would be kidnapper wouldn’t just cut off the body part with the scan. If this was possible, it would be 100 percent worth it to save people who are killed during a kidnapping or kids who are molested by strangers that take them.
Are you kidding, too? No, it would not be "100 percent worth it to save people who are killed during a kidnapping or kids who are molested by strangers that take them." How does a barcode prevent a crime before it happens? Even if it could do so, no, it would certainly not be worth turning us all into little robots, any more than we already are.
