What consists of criminal mischief in NJ?

Recently me and some buddies of mine had a bit too much to drink and thought it would be wise to smash a few mail boxes....We got caught. All I know so far is we could be charged with Criminal Mischief in the 4th degree. I've been doing a lot of research and found that 4 conditions must be met in order to be charged with this.

1. That defendant damaged tangible property;

2. That the damaged property belonged to another person;

3. That defendant acted recklessly or negligently when he/she damaged the property; and

4. That the damage to the property was caused by defendant's use of fire, explosives or other dangerous means.

We are guilty of all except for the 4th. No items/weapons etc were used (or fire or explosives). NJ law states that in order to be convicted of criminal mischief, all 4 circumstances must be met.

I'm basically asking, do we have a chance to not get charged with criminal mischief considering all 4 conditions were not met?
