Another way would be to stop letting extremist Muslims into the country in the first place and if any already in the country display these tendencies deport them and all of their famiy back to their country of origin.
One Muslim country after another are attacking ,harrassing ,persecuting Christians and driving them out of their homeland and very little is being reported about it in the media ,why not ?
There seems to be a trend not to offend our Muslim brothers and sisters so as not to occur more atrocities to be committed by them.
