Marines embody Justice, and killing somebody to obtain their Devil Fruit is very under-handed. Only the Chiper Pols would do that. Besides, I don't think they know which pirate has which Devil Fruit, and as the most organized and spread force in the world, they'd have little trouble finding them. But even so, I don't think Vegapunk has informed them of this discovery. He is a very mysterious character... he agreed to let Kuma defend the Sunny for one whole year even though that went against the orders that the Marines were given. I believe he loves science, but does not trust the World Government.
