Well....should you invest in a city where the people elected a woman with foreclosures, liens, judgements, garnishments, ethical violations from the state ethics board,  misused a city credit card, went three years arrears on her federal taxes all while yelling for other people to pay "  their fair share, " left skeletonized dead bodies hanging over Canal St for months on end covered only by a tarp until the wind blew it off to reveal to our horror her blatant disrespect for human dignity?
