Its not strange, its lying with statistics.

I understand why someone would want to use a balanced distribution scale (even though you get weird boundaries sometimes), its so you get the most dynamic visualization and take full advantage of your color library.

What doesn't make sense is redefining the color scales boundaries every time the year changes. As illustrated in this visualization, it intends to lead the viewers to believe violence is getting worse, when in fact the last years maximum number is 5 times lower than the first year.
