...we waited 20 seconds long, and then i fired 3 warning shots at him..
As a detective, the correct procedure for force testing, is to usually give a suspect 2-3 warns
in chat (e.g. Player X come test warn 1, ...warn 2) and if the suspect still hasn't responded or refuse to test after the 3 warns, you can then call a KOS on that player. "Warning shots" are traitorous acts as innocent and if done by detectives, can also be considered ARDM.
