Some states have laws against gambling because, in general, gambling harms the community/society.
As does my state, NC. But our Governor has been pushing for a lottery since before he was elected, and our state allows gambling on an indian reservation and in churches and schools through bingo and raffles. So, gambling is allowed to an extent here.
But back to my question, who is the victim in my crime of possessing a lottery ticket?
I contend there is no victim, and many crimes are victimless.
Back to my answer. We do not write laws based on the individual.
Why must I drive 55mph on the highway? I'm capable of safely driving 70mph, the road was built for 70mph (before they reduced the limit to save gas), there's no traffic ... well?
