He'd Get Two to Seven

That's Jimmy Stewart. For grand larceny:

Checking with District Attorney Frank Clark in Erie County, N.Y., where the fictional Bedford Falls might well have be deemed to have been located,[New York Times critic Wendell] Jamieson confirmed Stewart's legal peril.

“If you steal over $3,000, it’s a D felony; 2½ to 7 years is the maximum term for that. The least you can get is probation," Clark told him. "You know Jimmy Stewart, though, he had that hangdog face. He’d be a tough guy to send to jail.”

That's okay for larceny. For the movie, I'd say hanging's too good for him.
