Bottom line is if you point a gun at an officer, or a even civilian for that matter their is a good chance that this will happen. Someone pointed out that the officers' were inexperienced, which is possible. I do not know a single person with the CPD. However, I do know a few people with extensive military experience that have had to make difficult decisions in the line of duty and they were turned down by the CPD for admitting to smoking marijuana in high school. Most law enforcement agencies would rather have someone with a degree who has never been in a stressful situation, rather then someone that has lived life and has experience related to the job.
If you listen to the audio of the incident, the officers' cease fire on multiple occassions and give directives to drop the gun before firing again. From the audio it appears that deadly force was used, they gave commands, evaluated the situation, and decided that deadly force was still needed. I would be more concerned if only one or two of the officers' felt this level of force was necessary, but the fact that all six of them responded in the same manner says to me that it was probably justified.
I'm anxious to see if the DA's Office steps up and charges Christina Young with Perjury. However, its more likely that they play the buddy system and let it ride.
