Tax evaders take on US government

"Show me the law!" says Ed, a trim 64-year-old with a silver mustache, whose forehead crinkles when he gets heated. The Browns stopped paying income taxes in 1996. They say the Constitution and Supreme Court decisions support their claims that ordinary labor cannot be taxed. But a judge ruled against them in January, convicting the Browns of conspiring to evade paying taxes on $1.9 million in income from Elaine's dentistry practice.

Now, the Browns say they're in a battle for freedom, and it just might end in bloodshed right here, in a towering turreted house with 8-inch-thick concrete walls and an American flag fluttering over the double-car garage. They have garnered national support, with blogs devoted to news about the standoff and supporters regularly showing up on the couple's doorstep with groceries.
