One thing Al Snyder wants to make clear: His boy fought and died for freedom in Iraq, but not for the right of some "wackos" to spew hate at soldiers' funerals under the protection of the Constitution.

"It's an insult to myself, my family and the veterans to say this is what our military men and women died for," Snyder says, barely concealing his anger.

Yet more than four years after the death of his only son, Matthew, Snyder is in the middle of a Supreme Court case that raises almost precisely that issue.

The court is set to decide whether members of a fundamentalist church in Kansas who picketed Matthew's funeral with signs bearing anti-gay and anti-Catholic invective have a constitutional right to say what they want.
