The Press and Statute of Limitations Bogusity

I keep hearing press reports connected with one asserted crime or another, that because the allegations happened long ago, they are "past the statute of limitations", as if there's a national criminal statute of limitations that pertains to state criminal cases..

There isn't.

Many states do have statute of limitations for criminal acts.  But not all. Wyoming doesn't.  I'm sure we're not alone in that either.

Most recently, this has come up concerning the various news stories about Bill Cosby.  I won't go into that, but a common report is "the alleged actions are past the statute of limitations".  Maybe they are, but if they are, they're past the statute of limitations in California, presumably.  They wouldn't be past the statute of limitations in other locations, if the alleged acts allegedly occurred there, depending upon the location.
