I suppose there's not many other ways to incentivise people in America other than offering them money. Seems like simply informing for the overall benefit of society wouldn't be incentive enough ...

>I suppose there's not many other ways to incentivise people in America other than offering them money

that about sums up the problem for Americans and the world have in general.

The problem is about how it is enforced. Vigilante-type crowd sourcing to enforce laws isn't the right way to go about this.

> Vigilante-type crowd sourcing

...is a contradiction in terms. People who report things to the responsible authorities rather than taking violent enforcement action themselves are engaging in exactly the behavior vigilanteism is defined in opposition to.

> Do you really think citizens policing each other is a good way to enforce laws?

Irrelevant, because this isn't citizens policing each other. (Though, I will note in regard to your question that the alternative of having a distinct subculture separate from normal citizens that inevitably views themselves aligned against the citizenry policing the citizenry is far worse than citizens policing each other, but yet that's what we mostly do.)

> This is going to get ugly real fast. It creates division and disharmony in a community

Lawbreaking creates division and disharmony in a community.

> Read history.

I’ve read quite a bit of it; but I disagree with your implicit analysis, which attributes to a method of enforcement that most modern societies have chosen for some laws problems that stem not from that source but from the particular laws which certain repressive societies enforced using that and other methods.

What are your other ways?

Yeah because the Stasi were real stickers for the environment.
