I'm sure that someone stopping a mass-murderer in an LDS temple would get excommunicated . . . not !
You might be surprised.
The Mormon church has been known to turn a blind eye on occasion. Take polygamy for example. They outlawed it a long time ago because congress wouldn't admit Utah as a state until they did. They say they'll excommunicate polygamists but there are lots of them. The church just looks the other way. This is the Utah based church, not one of the fundamental offshoots.
