Will shooting in Missouri Church get Churches to reconsider Concealed Handgun Ban?

I found it interesting that the left-leaning Daily Kos seriously discussed the issue of gun free zones:

The fatal shooting of three people in a Missouri church on Sunday promises to renew the debate over concealed weapons laws.

Under the state's "conceal and carry" law enacted in 2003, Show Me State residents can bring firearms into places of worship (among other places), provided they get permission from their pastors. Whether the gunman or any of the assembled in the First Congregational Church in Neosho had received the blessing to pack heat in a house of God remains to be seen.

Among Missouri's Catholic churches, at least, such permission is unlikely. In the wake of the passage of the conceal and carry law, the Missouri Catholic Conference prescribed guidelines for churches in the state. Among its recommendations that each church should distribute a written policy to all employees and parishioners, as well as post a sign of at least 11 inches by 14 inches announcing that all weapons are prohibited within. . . .
