Medieval...it is interesting that Hamtramck, MI represents one of the most Islamic communities in the US at about 47% Muslim as indicated in the below article. Half of the City Council may be Muslim. Muslims like to not assimilate and to exist in parallel societies as a base for foraying out on their mission of conversion of surrounding territory to Islamic rule, culture, etc. Muslims would like to isolate themselves from Detroit and surrounding areas and have better control of their cultural territory as it is developed...a security wall is consistent with creation of a primarily exclusive Islamic community in which the non Islamic components are removed as rapidly as possible:
