Appologies, my last post sounded rather like a flame, admittedly I'm not in the best mood in the early mornings.
Adamantine worded it pretty well, but apart from that we simply don't have the people to patrol every tradelane. Having patrols of 5 fighters is all well and good, when you have that many fighters. Sure, the LN is big, but with timezones there are huge dead shifts. All the powersmugglers head to Manhattan, and since they're the ones we're concerned about, not to mention it's the closest thing to a chokepoint in NY, that's where single members of the LN prefer to operate until they receive backup.
