这个案子的重点在于警察说接报出警， 很可能是他的家人受到这个男子的威胁而报警的。既然家人都觉察到危险危险，这男子持刀不停警察命令停下持续冲线警察，警察也会觉得在极度危险的状态下开枪。报道说是在男子冲到距离警察10feet时。这个应该是在他们的警察开枪手册里规定的情况之一。

The shooting occurred before 4 p.m. as officers responded to a report of a person with a weapon, police spokesperson Tanya Little said.

Officers were called to the Cobbs Creek neighborhood and encountered the man, later identified as Walter Wallace, who was holding a knife, she said.

Officers ordered Wallace to drop the knife, but he instead “advanced toward” them. Both officers then fired “several times,” Little said.
