To shoot a target, the shooter needs to establish a line of sight.

Often times, the target gets the same line of sight, if they choose to return fire, for whatever reason.

Sometimes, they may be just pissed off at getting fired upon.

You should have read the thread before commenting. Anton was setting up his position 600 feet from the hotel, so not the same lines at all. Anton would have been shooting upwards at a much steeper angle than Paddock was shooting downwards.
