Bring in more police and fund it with arrests and tickets. A zero tolerance policy for alcohol and house parties would have taken care of this. But since the police preferred to just break up parties rather than make arrests it ended up getting bigger and bigger. Hold the owner of the property responsible for what happens. If the property is rented then go after the landlord. Right now, there are no consequences for someone to throw an out of control house party any time of the year, let alone VEISHEA.
