A sheriff of a small town told me how they ended up spending thousands of dollars to SWAT team which he thinks he will never use. The reason ? After some school shooting in another end of USA the folks of his county wanted to know how their LEAs plan to defend the local schools. The correct response here was that they do not expect such law probability even and even if it happens there is very little they can actually do.

But public does not like it and hence they had to put together a fake plan and waste money. Which could have otherwise gone into preventing real crimes.
