Lazier? Pulling out the taser as a first resort? Did you see the entire altercation? All she had to do was sign the ticket, she said he would have to arrest her. He man handled her when she didn't get out of the road, and hence out of danger, fast enough. He tried to cuff her and she resisted arrest. He man handled her when she tried to flee by walking into the traffic. He warned her at least 3 times that he would tase her and she dared him to do it. SHE HAD AMPLE OPPORTUNITY TO AVOID THE TASING. Every time she was given a choice to lower the tension in the situation, she made the wrong choice.
Usually people do not have difficult choices when dealing with the police. The police need to control the situation. If you let them know that you are not challenging their authority, situations usually get resolved with no altercation. That could have happened in this case but she chose otherwise.
