Why are US laws so messed up?

Stephen Collins (the dad pastor) admitted to past sexual abuse of three female minors" in 1973, 1982, and 1994. One minor under the age of 14. And because of laws he escaped criminal charges due to statute of limitations, how is there a timeline on a crime that can destroy another person from the time of the crime until death it's unfadable to me that you can rob a bank get caught on camera so it's clear evidence of you doing it and stay in hiding for years and than ride in your new ferrari outside the police station holding a bag of money because it's not illegal anymore due to statute of limitations.
