That a city council voted unanimously doesn't make it a good idea. What if they voted that the city wasn't going to enforce laws on assault? Who's going to be held responsible when they get a "refugee" that is a really bad apple, and does something vile?

If any city is going to play this game of chance with their citizens and finance, they should have to undergo a very thorough screening of their finances they next time they're asking for more money.
