Really? Care to post which law it violates? Care to post any case law on point? You are perfectly within your rights to investigate suspicions before going to the police.Not at all. The Church wants to immediately investigate any suspicion of pedophilia, to determine whether the charge has merit. If it does, then the perpetrator can be dismissed and turned over to the police.Sorry, but thats illegal. You go to the police first.
If you suspect your neighbor has been killed you are free to investigate a bit before dialing 911. You could skip that an dial 911 immediately. Its your choice. No one gets locked up for knocking on the neighbors door to see if they are OK before calling.

I don't know if there is a like statute in state law, but:
USC Title 18, Part 1, Chapter 1, Section 4 Misprision of a Felony
Whoever, having knowledge of the actual commission of a felony cognizable by a court of the United States, conceals and does not as soon as possible make known the same to some judge or other person in civil or military authority under the United States, shall be fined under this title or imprisoned not more than three years, or both
Also, an attorney told me once that he could lose his license to practice if he failed to report a felony. And a police officer I knew also said he was required to intervene in any felony in progress even off duty and had to report any felony he observed.
