I live in southern Michigan, and recently a evangelical church in Lansing had demonstrators storm into their services.  There was vandalism, threats, and all kinds of crap going on.  Haven’t heard about this?  Hmmm.

Our stake leaders are concerned about this happening to one of our Mormon wards, and are giving some instructions about what to do.  Their advice is to:

Warn the members that this might happen.
Do not retaliate.
Have everyone stand and sing hymns until they go away.
Get license plate numbers and pursue prosecution.

I am afraid that this is not as far-fetched as it might sound.  Is the above advice any good?  What would you do?
