At many nursery centers/day care centers, they have a computer at the door when you walk in; you have a pin number that you punch into the computer, which unlocks the door to the center. Why don’t schools use this system vs what they use now?

They should all wear uniforms with numbers on them as well, preferably orange in color, for if there was an incident, one could easily identify who is the assailant and who is the inmate student. Keep them there for a minimum sentence period of 8 hours per day, for 12 years, only to be released to the yellow cans for prisoner transport home.
