The same thing applies to you, you were drinking and you made a stupid decision by stealing and destroying those signs.
You have also, driven a vehicle while intoxicated, again .. very, very stupid because drunk drivers kill people.
You were lucky because a police officer intervened and took you out of that vehicle, possible saving someone's life, no one will ever know, will they?
Habitual drinking is dangerous, you hurt yourself and others. I was not going to allow any escalation.
People in glass houses should not throw stones.
