Churches are going to have to be like courthouses and the Oklahoma State Capitol. You can't enter them without going through a metal detector with at least two-armed officers monitoring. The same with schools, malls and other places where people gather. But that takes money, so I doubt doing that is going to be more common than it is now, unless Republicans want to legislative billions to provide funding. However, if mentally ill and evil people resort to using plastic guns, it would end up a waste.
