I've heard talk of his insurance company picking up the tab once they know the final figure....I'm sure it will be taken care of by his estate/family/insurance. I think most of it was paying for security around the city due to the huge influx of "tourists."
According to the website, they anticipated 20000, but only 1,000 showed up.
I'm sure thats exactly what most of it was, but I still don't think the taxpayers should be stuck with the bill.
