Mission 86 – Steal Pops' Smuggling Money
Hop the fence and approach this building from the south- you may remember the place from wiretapping the junction box here. Take out the lone sentry to the south east and jimmy open the door.
The guy counting cash in the corner is hidden from the upper-level sentry, so take them out in that order, then mop up the remaining guys and destroy the goods.
The lone reason not to just chuck molotovs around in the first place is that you risk damaging the beautiful Deleo Capulet in the middle of the room. Exquisite. When you take all the cash, consider taking it too.
