Claptrap. The generators were reserved for the marathon in advance and the rental fees paid by the New York Road Runners association, which organizes the marathon.
If that group wished to donate the generators for another use, that would be extremely generous of them, but the idea that failing to give others something you have paid for is "stealing" is Barack Obama thinking.
Articles said the generators were powering the media setup for the marathon. It would be funny if the organizers contributed the generators to relief efforts and let the media go without power!
Only Libtards would refuse to offer these generators to the homeless, starving, and dying. But then, I repeat myself.
