For almost 40 years, Carole Hinders has dished out Mexican specialties at her modest cash-only restaurant. She deposited the earnings at a small bank branch a block away - until last year, when two tax agents knocked on her door and informed her that they had seized her checking account. She has not been charged with any crime. The money was seized solely because she had deposited less than $10,000 at a time. Using a law designed to catch drug traffickers ... the government has gone after run-of-the-mill business owners and wage earners without so much as an allegation that they have committed serious crimes. The government can take the money without ever filing a criminal complaint. Richard Weber, the chief of Criminal Investigation at the I.R.S., said in a written statement ... that making deposits under $10,000 to evade reporting requirements, called structuring, is ... a crime. The Institute for Justice, a Washington-based public interest law firm ... analyzed structuring data from the I.R.S., which made 639 seizures in 2012, up from 114 in 2005. Only one in five was prosecuted as a criminal structuring case. Law enforcement agencies get to keep a share of whatever is forfeited. This incentive has led to the creation of a law enforcement dragnet, with more than 100 multiagency task forces combing through bank reports, looking for accounts to seize. There are often legitimate business reasons for keeping deposits below $10,000, said Larry Salzman, a lawyer with the Institute for Justice. For example, he said, a grocery store owner in Fraser, Mich., had an insurance policy that covered only up to $10,000 cash.
