You are a PROFESSIONAL Assassin

Since you didn't see the target when you drove past the Bar you decide to enter the Bar to see if he's inside.
You put your rifle back in the car incase anyone just happened to go on the roof however unlikely that may be.
You walk into the bar and look around as if looking for the toilet and theres no sign of the target. You go into the toilet to make it look natural as to why you were coming in. You decide to call it off untill your walking out and you happen to see the target entering the building.
Why hes this late you dont know and you dont care, all you know is hes in here now and he's going to die.
You go back to the car, collect your rifle and head back up to the rooftop.
Another 2 hours pass its now 3am, your getting tired laying there can be exhausting having to stay alert every second.
Suddenly the target stumbles out of the Bar drunk, you think how he can be the son of a 'respected' politician but quickly push all thoughts out your head. Your target is there, hes in sight, you hold your breath and take the shot....
It hits him in the neck, you see him collapse and shoot him again to be sure he's dead. Because its dark, deserted and the people left are drunk, anyone who sees him just assumes hes fallen unconcious from to much drink. You take apart your rifle, put it in the car and head on home...
