If part of an organized ring I wonder how well acting as a dedicated decoy would pay off strategically.

Deliberately "cry wolf" with legitimate but shady looking shipments while other members carry out business. Of course that would make them and the organization lose their illegitimate income and the police likely outnumber them in particular even if there may be more smugglers total.

Of course long term thinking and crime for profit don't usually go together - quick gains and jackpots are the temptations in the first place.

Right or wrong aside, this is already illegal where I live by the same reason it is illegal to be sober and leave a bar as the designated decoy (ie: pretend to be drunk to distract an officer watching the bar for drunk drivers).

Larger scale smugglers/producers definitely do this, and yea, if you're a middle management drug dealer in one of those organizations, that's probably the play. But also they'll be getting spied on by federal/international organizations with better tools than physical magnetized trackers.
