…and does he get summarily fired? ‘course not! They’ve got that union contract that prevents departments from getting rid of psychopaths with badges. No, he’s bee “indefinitely suspended” — so he’ll be back as soon as the storm blows over, or he gets another job in another department.
Sorry, the proper response here, when some lunatic threatens you with a gun, is to blow his damned skull open. Badge or no — you aren’t some special class of person, you aren’t more important than the people you purport to serve.
For all those “officer safety is paramount” types — you put the uniform on. You strapped on a gun. You chose a dangerous career. If you can’t do it without APCs and air support, then maybe you should go take up woodworking.
