SWAT teams, armored vehicle seen near Brown compound

The AP reports:

Neighbors of convicted tax evaders Ed and Elaine Brown reported police SWAT teams and at least one armored vehicle converged on a field near the Browns' Plainfield (New Hampshire) home this morning.

Federal and state authorities haven't commented on whether they are moving in to arrest the fugitives, and the local police, the governor's office and the U.S. Attorney's office referred calls to the U.S. Marshal's office, which has been negotiating with the Browns since their tax evasion conviction in January.

You mean taxes are "voluntary contributions"?
