That's seems to be pretty much always the case. I suspect grant money has something to due with it.
Lawrence Keeley tells a very interesting story in his book War Before Civilization (which I highly recommend) about getting a previously denied grant by changing the word "fortifications" (implying warfare) to "enclosures" (implying a peaceful purpose) in his grant request. The illustration he provides showing the distribution of arrow heads that he found around one of the "enclosures" shows just how rediculous the peaceful interpretation is.
