instead of isolating the uchiha to the outskirts and giving them control over the police force. Tobirama should have developed a sealing jutsu similar to the hyuga main family's sealing jutsu meant to bind and restrict the uchiha and if need be bind their sharingan. then in the middle of the night he could have sent an elite group of specially trained ANBU to forcefully put the the curse mark on the uchiha's fourhead.

after that if the uchiha ever try a coup the seal would activate binding absolutely every uchiha who has a sharingan.

another option is that the seal could be designed to respond to evil thoughts. if an uchiha begins to fall into despair via the "Curse of Hatred" the mark would activate and purge their minds of the evil thoughts by placing a mental block preventing them from remembering what gave them the evil thoughts.

he wouldn't even need to create the special anbu group he could have simply offered his intelligence to work together with the uchiha on how to keep the curse of hatred in check. this way the uchiha could willingly put the mark on themselves
