NPR has a good story about law enforcement agencies seizing drug assets. It can pay for itself.
The kicker is this: police prefer to come in after the drugs have been sold because it's better for police to seize the money rather than the drugs. If police seize the drugs, the drugs are destroyed. If police seize the money from selling the drugs, they get to keep the money.
Talk about a dirty partnership. I thought robbing drug dealers was a crime.
