Quite. If cops have cameras attached to their faces all the time when on duty, then that should be recorded, stored and made accessible to all pertinent parties.
For instance, if you are arrested or searched by an officer, you or your attorney should be supplied with the footage from all officers who arrested/searched you.
If misconduct complaints are raised against an officer, this system should be made available to review their actions in the period in question.
If they roll out this without doing any of these things, it would be a sham. I have no problems with honest upstanding cops, but they are public servants whom we give a great deal of power, their actions should be accountable to us. Too frequently when one cop does something wrong, the rest clam up and cover ranks, they should be gagging for a system that records precisely what events occurred.
