Right now it seems that a lot of people feel unsafe and even a bit paranoid because they feel they can get hearth-summoned and killed for a non-crime by any overzealous ranger that happens to spot the clue.
So what am I proposing to bring some safety? Control over clues on claims by the claim owner or lawspeaker in case it's village claim.
How would this system work? Well, the claim owner must make a clue public before anyone but him can harvest it. What about clues that he can't see? A ranger that spots the clue should be able to place a request for the clue to be made public. This would reveal the clue to the claim owner so he can make it public, but wouldn't allow the claim owner to harvest it if he normally wouldn't be able to. Of course, requests should still be placeable even if the claim owner does see the clue.
With this system you could punish criminals on your property with impunity, and even killing one on public village ground would be safe as long as you explain to your lawspeaker what's that murder clue doing there. Committing crimes out in neutral area would still carry a significant risk, so if a thief makes it out of the village he can at least get his revenge if he gets caught and killed.
