One certainly has an interest in putting a halt to burglary in your neighborhood, especially when there is reason to believe said burglar already visited you (and yes, sometimes this kind of lightning strikes multiple times).
In this case, even though the man technically violated a "reckless discharge" statute, the police should have just let it go, unless someone else in the neighborhood complained (a ricochet might have gone through someone's window, for example). A verbal warning would have sufficed. I really hope they drop the charges.
