A Brooklyn performance artist’s latest project has raised the ire of family members of 9/11 victims, New York Mayor Michael Bloomberg, and at least one New York tabloid. Kerry Skarbakka said that he wanted to get inside the minds of the people who died leaping from the upper floors of the World Trade Center before its final collapse, and his chosen method involved donning a business suit and repeatedly leaping from the roof of Chicago’s Museum of Contemporary Art (he wore a harness), while photographers below took pictures of his fall.
