It's human nature to ignore unreasonable laws.
A call to the cops for rowdy behavior in public will usually put a stop to it.
- Thus, it is unreasonable 'law' to prohibit drinking a beer at a picnic in a public park, solely to prevent 'bad' behavior. -- Reasonable people scoff at stupid laws.
They shouldn't be on the books.
I was being a little facetious but as a matter of fact I do agree there are too many laws. I don't agree that not allowing drinking in a public park is one of them.
