As you've pointed out yourself, HOYHA was paused for 31 second. You started shooting him few seconds earlier, which means you've killed him around 28th second.
Rules allow cops to kill non-threat criminals if they are paused for >30 seconds. You were off by few seconds.
Next time do /i [name] to see for how long a criminal have been paused before shooting them.
Since the report on you was valid + no severe punishment was given, I'm gonna DISMISS this complaint without any additional action.
