Context: This is a world inhabited by intelligent, non-anthro animals, some of which have decided to outlaw hunting and eating prey in favour of living in harmony and cooperating.
They have a zero tolerance policy for predation and it is criminalized extremely heavily. Depending on what species or taxon you are (all animals have the right to be tried by members of their own species and taxa, and they are responsible for carrying out sentences of their own kind too), First Degree Predation, where you personally kill then eat an animal, is the only crime that formally carries the death penalty. Regular first degree murder where you "merely" kill an animal without intent to eat them only has a maximum sentence of life in prison without parole. Second Degree Predation (aka Simple Predation) is where you obtain meat with the intention of eating it without personally killing anything, carries only a mandatory fixed term prison sentence in addition to losing certain freedoms post release.
However, their laws on the issue is very much based on intent as that is their philosophy, that because they are all sapient and no longer bound by their natural hunter instincts, they are responsible for their own actions. You don't have to actually eat the prey you killed to have committed First Degree Predation, and the inverse is technically true as well, where if you kill an animal for some other reason and only after they're dead do you decide to eat them, then you're technically only guilty of murder and Second Degree Predation instead of First Degree Predation. There are also legal ways that certain animals can obtain animal tissue, for example, as skin grafts and organ transplants, autopsy and forensic investigations, or for general research. Because animals handling tissue in these cases don't intend to eat it, it does not fall under Second Degree Predation. However, if you buy animal meat and later decide not to eat it, that's still considered predation.
Especially with the nature of eating and digesting food, law enforcement only has a very small time window to order a suspect to undergo lab testing of what's in their belly where it will actually show a positive hit for animal tissue, so my original thought is that the intent clause is meant to make prosecuting predation easier, since they wouldn't need to actually prove that the accused has animal tissue in their digestive tract at any point, just that they wanted at some point for some form of animal tissue to end up inside them.
I know there are many real life laws that use intent in a similar way, but I don't know how courts actually prove intent beyond a reasonable doubt. Can anyone who's delved more into the legal side of worldbuilding comment on how the courts in my world might prove (or disprove) that someone intended to eat another animal when they do not have direct evidence that the animal was indeed eaten?
You could have an emphasis on experts who investigate the scene and make claims as to whether or not the scene was conducive to predation. For example, if there was tall grass and a tree, then it'd be a great place for lurking. If it was at a watering hole commonly used by both animals then it's more likely to be social mores. Then you could have a discourse about corrupt officials versus virtuous officials.
Star nosed moles as Detectives and Crime Scene investigators as their sense of smell is insanely good. Does the accused smell like the victim? Does the accused animal's property smell like the victim? Would there be any reason for the accused animal's person or property to smell like the victim?
Also, having situations where "predator" species are being framed by "non-predator" species because nobody would expect Jessica Rabbit to be a serial killer and all the blame is directed toward the family of foxes that live in the neighborhood.
