Whatever these robbers owned should be sold to repay the cost of the ammunition used to removed them from the gene pool. If more money is needed their carcasses can be sold as maggot food.
They didn’t sound like very good robbers. Doubt they had much!!
The young mobsters I knew growing up with at least put some effort into it. Scouting, planning. These guys were bozos.
What they were doing was wrong but being as I wanted to live past 25 and didn’t trust the police, I kept my mouth shut.
