Someone else said it was 5% of arrests, not thefts. If so, I would expect organized groups to be less likely to get caught, and to steal much more in each robbery.
Folks living in a tent aren’t typically the ones getting caught with a warehouse and 18m or 30M in stolen goods, which has happened in LA and Chicago respectively. These are organized crime rings running fencing operations at heart.
The same thing is happening in agriculture, though it’s really under reported.
