US Police going nuts

BBC wrote yesterday about some quite interesting. US police handcuffed a five year old girl.
My first reaction was “WTF??, They handcuffed a kid??”, and after some seconds I though this is probably just some “Homeland security”.
Who is stupid enough to handcuff a 5 year old girl? The incident is under investigation, but I’m sure this happens other places in USA too. Something is totally wrong with that country, and most disturbing: most of the americans seem to not care. If they cared, they would not have Bush as president.

It’s just sick!
