What is mailbox baseball?
Similarly one may ask, is mailbox baseball a felony?
A jury this spring found Reihel not guilty. Because the postal service considers mailboxes to be government property, destroying one is a federal offense, punishable by up to three years in prison and a fine of $250,000 for each charge.
Regarding this, how do I keep my mailbox from being smashed?
Encase your mailbox in a protective wood or metal casing. Using scraps of 2-by-4 lumber or rebar, build a cage or house for your mailbox that will withstand a beating by a baseball bat. Attach the casing firmly to your mailbox and post; it won't work if the vandals can easily remove it.
Intentionally hitting a U.S. mailbox may constitute a federal crime, as they are protected under federal law. You may also be charged for accidental damage if you cause it while committing another crime, such as driving while intoxicated.
