As I've already mentioned that before you conduct any operation you do your reconnaissance first to make sure that your target is there.  If you choose a place and you realise that your target is not there, then you won't go there, you only will go there when you know that that place is your target and you don't just do a reconnaissance for one day, you do for days to make sure, to be 100% sure that that's a legitimate target.
