This is really helpful. I’ve been wanting to get started, like OP, but knowing how to do it feels overwhelming.

Thanks!

TBH, this sounds like something to ask a lawyer. Since you’re in France, there may or may not be statutes that protect witnesses or people trying to cooperate with law enforcement, and a lawyer who’s familiar with your laws would be able to give you correct advice.

And in the event they give you bad advice, there may also be protections regarding “following the advice of counsel.” In the US, following in good faith some bad advice from lawyers can result in protections or immunity from certain charges.

So do yourself a favor and get some proper legal advice.

Never heard of it, but now I’ma add it to my watchlist
