It gets worse with felony disorderly conduct... you could end up imprisoned for between one to five years depending on the specific charge, and be hit with even more significant fines. Odds are if you are caught smashing pumpkins on private property you'd face a fine, community service, or a slap on the wrist. Odds are you'll be hit with a disorderly conduct charge or vandalism. (If they are caught)No matter how young or old you are, your “pranks” could result in you facing disorderly conduct charges if you are caught breaking the law.
