August “Bulldog” Perotta
This target is hidden in a back alley with some slot machines. There should be a lot of cash to be collected here as well. Take out the sentry then you can sneak inside the slot machine storage shed and move from there. Otherwise, use grenades to take out most of the enemies; take note that attacking this joint may trigger nearby enemy positions and they might flank you from behind so keep an eye on your mini-map as well.
Rocky Torani
Rocky’s in a back alley with scattered guards. With a silenced weapon, you can breeze through them and when in range, just use a molotov or grenade to kill him and several of his guards (as well as some of the gamblers) in one boom.
Shane Fordham
Shane is located outside the baseball field. He can be sniped at the right angle; just be prepared to use the phone operator associate just in case nearby witnesses attempt to call the cops or the alerted sentry to call in reinforcements.
