That the government of San Francisco, America's most liberal city, on November 29, 2022 by a vote of 8 to 3, authorized robots to have life or death authority over citizens indicates the extent to which Americans have been dehumanized.  Perhaps this dehumanization is the consequence of many decades of Washington slaughtering people from Vietnam through Serbia, Afghanistan, the Middle East, North Africa to Ukraine. Having blown up villages, weddings, funerals, children's soccer games, medical centers, farmers, and countless women and children, it is not a big step to siccing killer robots on citizens.

Another reason for this development is the likely payment of bribes to the San Francisco government by Artificial Intelligence corporations that want to develop a market for their AI products. Robots have an upfront cost, but unlike policemen do not have to be paid salaries and provided with health care and retirement pensions.  Substituting robots for police officers will be hyped as a cost reduction measure.  The fact that it is the final dehumanization will go unnoticed by people determined to line their own pockets.
