How can i solve expression like 42÷-2)

In 1944, the supreme court upheld the authority of the u. s. government to order the internment of a minority group in the interest of national security, even though there was no evidence that any members of this group were disloyal to the united states. should the same policy be applied today against u. s. muslims or muslim immigrants? why or why not? are these forms of internment different from native reservations? if so how? if not, why?
