scipio/Grahame I think Jeremy Bamber was very confident he was going to walk free this is why he adopted his stance of being so cocky and arrogant.
Some people act like that even when they shouldn't because they can't help it. That is why lawyers try to reign their clients in and try to control questioning of them.
People who act that way usually have insecurity issues and are so busy acting like an idiot they end up shooting themself in the foot. While I am being figurative for some jackass with a gun that can also be literal. Many a gun accident has been at the hands of someone cocky and arrogant and thus careless. How often do you hear about accidents even from supposed experts.
A friend was dating a cop (she was as cocky as a male cop and though my friend hated cops she had a nice body and slutty little sister who joined her so that was that) and she drove over in her car and uniform one day and let us play with the car and see her gun. She dropped the clip beforehand. I grabbed it first and decided to make sure it was empty so pulled back the slide to look in the chamber- a bullet popped out. If I didn't do that I guarantee one of my jackass friends would have fired the round somewhere in our house- probably into me because I have bad luck. Needless to say that took some steam out of her sails. She hated me anyway though so it didn't matter. (My friends liked pot but she could not be around it as a cop so anytime they smoked she stayed in another room) I would not partake so it was just me and her. I tried talking to her a little he first time but she had no interest and would not respond. I asked if she wanted to read one of our magazines or for me to trun on the TV or something and said I was annoying her isn't there something else for me to do. They eventually returned and asked us how we got along. She said we got along well and though I was hitting on her, quite harmless. I said she has as much personality as that plant, she just sat twirling her hair for an hour. (She really was, she sat in a chair with her legs crossed twirling her hair with her finger and doing nothing else) She gave me the most evil look I have ever seen and if she didn't hate me before she sure did after that. I am brutally honest, my friends have always loved/hated that about me because it is a double edged sword. When you want to laugh your ass off watching me tell a dude 6'2" built like a linebacker that he looks ridiculous in a pink sundress and bonnet because he does and no one else has the balls to do it then it is great, but if you are a friend who likes that he dresses that way and embarassed by having someone tell him that then not so much.
She thought she was the most beautiful, best creature God ever invented and hung around with slutty friends who liked to party with crazy guys and that somehow made them feel good because they were being chased and desired. To me that means deep down she doesn't really believe that and puts on an act to try to convince herself and others including looking for losers who will reinforce what she wants to hear.
Cockiness is an act and usually a sign of seeking attention. People who crave attention try to garner it any way they can. Such people never realize that people are laughing at them behind their backs and most of their relationships not genuine.
It is sad in a way.
