There is no legal risk to reporting any crime.
I agree there is not supposed to be —but some people speak out of personal experience. They turn on the person reporting the crime. Don’t know how it is in other countries but try it in the US. Why this happens is because in all openness, they are sadistic and insidious and delight more in entangling an innocent person than going after a criminal and sometimes criminals have ties with the police or other agencies. Better to mind your business. Even when someone commit s a crime against you, the police wants to force you to come to your house to take the report and nobody is your friend. They tap your phone. They mark you and retaliate. Its better not to report a theft or a robbery or an assault against you. If you want to get involved, be ready for trouble. Even if you are only reporting, they still want to get you for anything they can so you will need to hire a private lawyer besides the DA just in case and that isn’t free. You have to experience it yourself to understand.
Of course, if they already have an agenda like going after somebody they don’t like, they welcome your reports to support their cause in that case but for something personal, don’t count on it.
