As someone who has been playing around on an indie LPI I think much of the problem stems from the fact that any and all LR having access to heavy ships such as gunboats. It's kind of detrimental to RP (IMO) when you see a LR gunboat pirate 20k from Manhattan. Such a thing would of course attract the attention of LN and they would be there in 2 minutes sharp, but of course a lot of the times the LN simply don't have a presence in NY (apart from NPC's who don't react to that kind of stuff).
Now, I would love to do something about this gunboat, but with my little Liberator the best thing I can do is trying to notify traders who are about to go on the trade lane that there are pirates active in the system. Often traders will ask me why the hell I am not doing anything, and the simple answer is that I can't.
We also have those times when pirates in heavy ships just fly around Manhattan avoiding all gunfire from the NPC's and bases while trolling police like me who can't do anything about it with my smaller ship. Kind of detrimental to RP on this part as well. I guess because I am new to the server and all I don't have access to all the proper channels for calling in backup etc, but then again I am sure that many, many indie LPI and Navy players don't either.
