Embezzlement charges may come from the state of California or they may be brought by the federal government. Federal charges may arise in situations where the property allegedly embezzled is deemed connected to a federally-regulated market, a federal program or interstate commerce. At the federal level, cases may allege theft of supplies and tools to counterfeit money or other government documents, theft of artwork or failure to deposit or safeguard federal government funds.
You're an ordinary business person who happens to handle quite a bit of cash. The business could be a restaurant, a jewelry store, a pawn shop or some other venture that involves the need to put considerable cash into your bank account.
Imagine that you commit a criminal offense. Even if it may seem minor in nature in the grand scheme of thing (such as shoplifting a candy bar), it is still a criminal offense nonetheless. It could also be a serious crime (assault, drug crimes, white collar crimes), and as such, you would be facing serious penalties. In these situations, we are talking about local crimes that would be prosecuted by local authorities.
