Claire Wolfe (et al.) have had a run of posts about snitches, in part because of a more-or-less Free Stater pot activist-turned-informant-turned-semi-remorseful.
Lookit, three people can keep a secret -- if two of them are dead. Better you should make like Caesar's wife and doubly so if you are hoping to get an animal, mineral, vegetable or activity de-illegalized.
Does this suck? Yep. Life's not fair, get used to it.
Here's the deal: you can either sneak around, doing [$PROHIBITED] or you can agitate to un-prohibit while livin' in a squeaky-clean glass house. You can't do both; it doesn't work.
Assume you will be snitched upon. Strive to ensure the worst they can come up with is overdue library books or eye-rolling at Authority.
