100% justified... if it were the cop that tripped pursuing her, smashed his head on the curb, everyone would be saying "thats the risk of being a police officer"...

well, thats the risk of being a drug addict trying to flee the cops, regardless if you are cuffed or not... anyone remember the chick on Police Chases that was handcuffed and jumped in the officers car and took off endangering everyone on the road? pretty defensless little girl huh....
