Stallone is fine, they were long past the the statue of limitations in both States.
That being said, Nevada has raised the limit to twenty years, and California has done away with them all together, as have a lot of states.
While it seems like bullshit when something like the Stallone thing comes up, it isn't so bad when you look at the other side. Leaving them long or not having them at all allows for justice to be had in lots of circumstances.
For instance, here in the States, there have been lots of serial rapists (some of which turned into serial killers), child predators, etc.... that were let go because the statue of limitations had run out before a case could be made. Now with the longer limits or no limit at all, those people stand a better chance of going to prison.
