There is no easy solution for this.I think at the moment the only thing that can deter people is rising price of crackers.I know it’s hard for lot of people and especially pets to stay calm during the extended hours of bursting crackers but I guess you have to accept this being choice of majority of people.The more govt or the court tries to regulate the more people will try to find a way around just like how it is with all these warning messages and regulations the sale of cigarettes and liquor is still increasing.
