The Mayor of Boston was furious and reported that it cost the city somewhere in the millions to provide all the Emergency Service vehicles and personnel and I am pretty sure they are going to Sue Turner for those costs. The Fire Chief and Police Chief were also very upset.
You have to remember, in this Post 9/11 world we live in, that the two planes that crashed into the Twin Towers took off from the Boston Airport. In this day you cannot tell if a thing with blinking lights is something that is harmless or something that could go boom at anytime, and even if anybody touched it to see what it was. I don't think Boston is/was out of line at all in their response or fury. I am sure that if you were on you way to work, a meeting or just over to some friends house to get together and you were not able to get anywhere because traffic was at a standstill, buses where closed down, etc., you would be a lot more upset about it than just seeing or reading about it. Put yourself in those peoples places, and the humor goes away real quick.
