One thing, the police do not know at that time what offense the person they are chasing has committed and they will never know for sure until after the chase is over. These 2 people, girls or not, could have just killed someone and were running in fear that the body had been found. They would have the information that the license was suspended and yes poeple do run for this minor offense but there is always the possibility of a worse reason.
Another issue is that the girl grew up in Cobb County, she should know the reputation and practices of the police there and that is all the more reason to just pull over.
I can only blame the people who run, they are "adults" and are making their own decisions be them right or wrong. They did this to themselves, the police were not to blame. Also remember, there are more sides to the story than what we are seeing.
*my error, I should have read the article first and saw that they weren't from that area. I still stand by my opinion, plus this enforces it more. Had I been the police officer I would suspect something serious about people who are from another state, running from the police thru 2 different states.*
