The Supreme Court is limiting the government's ability to seize assets from people who are convicted of drug crimes but receive little of the illegal proceeds.

The justices ruled Monday that a Tennessee man convicted for his role selling iodine water purification filters to methamphetamine makers does not have to forfeit nearly $70,000 in profits.

Terry Honeycutt helped sell more than 20,000 filters at his brother's hardware store. Prosecutors said the brothers knew the iodine was used by local meth cooks.

Honeycutt's brother pleaded guilty and forfeited $200,000 of the $270,000 in profits. But Honeycutt argued he wasn't responsible for the rest since he didn't personally see any profits.

A federal appeals court ruled against Honeycutt, saying everyone who joins a drug conspiracy can be required to give up profits.
