Wrong. SCOTUS ruled back in the 80s, and reconfirmed in the 2005 Gonzales case that police have no obligation to pursue any particular crime, or protect any person from harm.
in “lawsuit politics,” SCOTUS and the law only go so far. the public relations mess in the discovery phase in the airwaves and net would be humiliating. the optics would be embarrassing. the state will settle.
in “lawsuit politics”, truth and law have little meaning. better to settle and let it go away.
so, they’ll need scapegoats to deflect blame.
