Easily break limbs... Too many video games.
And no, whether it was wrong or not obviously depends entirely on how you look at it.
Too many video games?
http://www.tbotech.com/police-batons.htmBoth of these police batons are highly effective for their intended purpose. However, proper training in their use is highly recommended to become most proficient. In both offensive and defensive uses, either of these police weapons can inflict serious damage including broken bones. Proper use of force should always be adhered to.
Spin hit with a tonfa (spin hit means you grip the side handle, swing, and as you are in midswing, let the handle a bit loose, which results in the baton spinning, gaining aditional energy) can shatter your skull if used with enough force, let alone breaking bones.
Now I dont know about you, but while they did not use this technique, they were still hitting him with enough force break his spine, and that guy was lucky that he was not on the ground with his face up, otherwise, I can guarantee you he would had a handful of broken ribs.
It is more likely you who lives in the world of video games where batons do nothing but x points of blunt damage, but the reality is that those weapons can even kill.
