Alma 14

Many people suggest that when a miracle takes place it causes the wicked to repent.  I find it interesting that when the prison walls fell and all the leaders of Ammonihah were killed, and Alma and Amulek walked alone that -

"...the people having heard a great noise came running together by multitudes to know the cause of it; and when they saw Alma and Amulek coming forth out of the prison, and the walls thereof had fallen to the earth, they were struck with great fear, and fled from the presence of Alma and Amulek even as a goat fleeth with her young from two lions; and thus they did flee from the presence of Alma and Amulek."  (Alma 14:29)

They didn't fall in fear and repentance, they fled.  I believe this would be the same today.
