Of your three cases, the officer in the first is facing criminal charges with up to 20 years in jail. Obviously the system works.
The second two were running around in public with realistic looking guns, and didn't quickly do what the officers ordered... Are you suggesting that people should be able to point fake guns at cops with no repercussions? Too many officers get killed on the job, already. Requiring psychic abilities in use of force decisions will make that number sky rocket.
