It's NOT about the technology...it's about HOW it is used and WHO uses it. Just because it's stated reason for use is X, doesn't mean that reason will not change to Y. Remember, even though we are only dealing with a school principal here, it is still GOVERNMENT....and government ALWAYS strives for more and more control over the individual. Once a system is established, the government has scant aversion to changing the 'rules' of that system in order to attain whatever goals it desires.
One thing I learned in my three decades as a field tech, EVERYTHING looks good on paper
