Do you actually succeeded with this? Because if not whats the point of posting it?
I tried to smartbomb them between their routes from station to station/citadel after concord puling and I failed even there, it seems they have multiple bookmarks they are changing frequently. So they will never fly in direct path you expect.
Seriously there is no point fighting criminals with current way how it works. They wll lose that ship anyway, they are prepared for it. And they usually bring enough ships to be sure they still kill the target even if one or two fails from w/e reason. Plus, why would you bother that someone else is going to lose their freighter, just make sure it is not you (again).
The only thing that bothers them is stealing loot from ship they killed. That’s where CODE drop tears even though they never admit it.
