St. Joseph, Mo. ? Members of an anti-gay group who have started protesting military funerals are calling an ordinance barring such protests a possible breach of their First Amendment free speech rights.

The St. Joseph City Council passed the ordinance Monday in response to members of Westboro Baptist Church, of Topeka, Kan., waving antimilitary signs at the August funeral service of Spc. Edward Myers.

The ordinance bars protests “in front of or about any church, cemetery or funeral establishment” within one hour of the funeral service.

The church’s leader, the Rev. Fred Phelps, contends U.S. soldiers are being killed in Iraq as vengeance from God for protecting a country that harbors gays. The church is not affiliated with a larger denomination and is made up mostly of Phelps’ family members.

Phelps is a disbarred attorney and several of his family members are practicing attorneys.

In a letter written Thursday to the city, the church points to what it considers vagueness in the St. Joseph ordinance.

Margie Phelps, a church member and attorney, said the city should define the phrase “or about” with a specific distance because it lends itself to “an overbroad application.” She said the protesters don’t want to “be on top of” the service and a typical acceptable distance is 90 to 100 feet away from the church.

“The first time I have to make my decision to litigate is the next time there’s a funeral of a dead soldier in St. Joseph,” she said.

Mayor David Jones said the city wouldn’t respond to the letter because the issue isn’t an official legal matter.
