Police have a name for it: Jugging.
Thieves follow delivery trucks through neighborhoods. Stay 2-3 stops behind. Watch where packages get dropped. Circle back after the truck moves on.
Denver PD detective: "We've arrested guys doing this. They hit 15-20 houses in two hours. By the time we get called, they're three neighborhoods away. We can't put a patrol car on every Amazon truck."
Why it's "unstoppable": Delivery trucks run predictable routes during the day when police patrol is lightest. Thieves blend in perfectly—just another car driving through. By the time victims realize packages are gone and call police, the thieves are long gone.
Recovery rate? Less than 2%.
Portland tracked this pattern for six months. Over 300 thefts directly linked to truck-following. Three arrests. Zero convictions.
One officer: "We know it's happening. We know how it works. But we're responding to violent crimes, domestic situations, traffic accidents. A stolen Amazon package? We'll file the report, but..."
The hard truth: Police can't stop what they can't catch in the act.
What actually stops jugging? Making the follow pointless.
When packages go into a locked vault mailbox immediately, thieves following trucks see... nothing to come back for. No visible boxes. No quick grab opportunity. The entire tactic fails at step one.
Customer in neighborhood hit 18 times in three months: "We watched them follow the Amazon van. Two hours later, hit five houses on our street. Skipped mine completely, Stonemore had already secured my package. They literally walked past my mailbox to steal from my neighbor's porch."
They can follow trucks all day. Doesn't matter if there's nothing to steal.
