What you'd actually need is that sniper, plus a couple of trucks to tow away the suddenly-driverless cars. And perhaps a clean up team for the bodies. Oh, and a lookout or two presumably. Maybe some heavies to fend off any unwanted attention. And with a team this big, you'll need some admin. Which means premises of some sort. So you'll need cleaners too. And maybe get a canteen - so, catering staff - but hey, people need to eat. Now, this is all getting quite large. Perhaps you'd need a dedicated HR team to keep track of it all. And of course there'd need to be management to keep it all running smoothly (ahem), and a board of directors for the more strategic, high-level stuff... Sorry. Getting a bit OT there. *slaps wrist*
