Yesterday on dust, there was a C4 planted in one of the small pathways right in the middle of the floor. The C4 had 20 seconds left on it and noone in the server had said anything about a C4 being planted. So anyways, I follow a player through the hallway and they basically step on the C4 and just keep walking and do nothing. I called a KOS on the player after I defused the C4 and they happened to be innocent. I'm just wondering if I was in the right to call a KOS for basically stepping on a C4 without doing anything.
