Spending time in jail or doing 30 days of community service would teach them a lesson they would never forget.
The victims' loss is not mitigated by the punishment.
At its best,
community service is forced labor for the benefit of the government, generally for a victimless offense or a crime against the owner of private property. At its worst, it's meaningless liberal feel-good bullshit.
In this case, the property owners would pay for labor benefiting the State, which would be an
incentive to the State for the crime to occur in the first place.
