Why Do U.S. Picketers Walk in Circles . . .

. . . while their British counterparts huddle together in groups?  The BBC News reports two theories.  First, says Donald Oliver of Blitman & King of New York, it's so they "can permissibly walk in front of a gate or entrance of a picketed establishment without blocking or impeding ingress or egress, which is prohibited by law."  Second, he notes, picketers can more effectively convey their message while on the move.  See Why Do US Pickets Walk in Circles?
