Sounds like an easy way to make some cash for an enterprising and unscrupulous individual.
1. Get a few crappy or broken guns. Don't spend more than $100 each.
2. Go to Newark
3. Plant them in people's cars/houses/etc. Try to focus on planting them on City Council members or in the Mayor's house.
4. Call it in.
5. Wait a month.
6. Get the cash.
