The idea that an officer can react in anyway he wants just because someone grabbed at him is ridiculous. Can he pull out his gun and shoot the person, when clearly they are no longer posing any threat? Clearly not. Obviously it didnt get anywhere near this, but the question arises, where do you draw the line?
I would like to think that an officer of the law, in this day and age, would have the training to assess this situation, even in the matter of seconds, and act accordingly. In my opinion, I feel that he could have grabbed the guy, even tackling him would have been more acceptable than throwing a haymaker.
When I watch the video, what I see is an officer who is annoyed and angry go after a guy that was grabbing at him. I do not see an officer that is afraid for his life or safety... maybe thats just me though
Keep in mind, its a police officers duty to serve the people, not the other way around.
Being drunk, acting like and idiot, and breaking the law is clearly wrong and deserves punishment... but i feel the "haymaker" was a bit over the top and not the proper conduct for an officer of the law.
