What is a good analogy for an argument where someone doesn't want to do their job?

I live in a picturesque midwest suburb that has had a tradition Fourth of July fireworks show for the past 50 years. This year the City Council decided to discontinue the show because hooligans from the poor inner city caused disturbances the past two years. There were two fights and some residents complained about trampled bushes. The Mayor said that the City feels the increase in hooliganism is the result of flashmobs caused by Twitter and Facebook. I am attending a City Council meeting this week to argue that discontinuing the fireworks show because of thugs is the wrong response and that we should figure out another solution. My argument is that it is the police and Mayor’s job to protect residents from thugs, not cave to them. What do you think? Also, if you don’t disagree with me, what is a strong analogy I can use with the City Council that underscores the rightful role of the police? What about the Little Rock Nine? Is that a good one? Or the fact that firemen don’t let houses burn to the ground because fighting fires is dangerous? Others?
