Leaving Liberty, while I'm sure is one answer, it may just be a short term answer.
My perspective on this topic is that this isn't really about the way you die or even the lack of RP between pirate and piratee but more the lack of necessity for RP on the pirates behalf and the need of so much more on the lawfuls side.
Thats why theres so many pirates and so few police/military. It's just easier with less hassle and less threats of sanctions.
RP comes with practice. Kick em hard enough and you'll get them there but having fun is a lot harder to get with so many restrictions placed upon you.
You may get some good insights and see the perspective from the other side in that thread and it might go some way to explain why there are so many more pirates and so few lawfuls.
