Earlier quoted context omitted.
Discretion works great for the privileged portion of the population.
You'll have to explain again how bad behaviour by US police generalises to professors. As far as I can tell this is simply a strawman. And even if it's not - the solution is to replace dickhead staff with reasonable human beings, not chain them with process so that everyone suffers.
The key here is, surveillance shouldn't be used against the students who are of low power, but instead against those who decide if the students succeed or not - the professors.
Trusting power is how one gets to significant asymmetry and gross abuses. Surveillance against those types is how you start to counterbalance "discretion".
