I rank this right up there with the "Animal Cops" shows. You have troopers analyzing the stiffness of a child's arms in the HOV lane, instead of perhaps observing and stopping a drug transaction, murder, rape, etc.
if a cars whizzing by at 60mph+.. how does an officer have the time to analyze the "stiffness" of the arm. and how would he see the arm of the child, most car doors come very high up and you can't really see whats going on inside below the window.
i call BS, cop just made up an excuse to pull her over.
You do realize that the "animal cops" are by and large non-profit organizations given some enforcement power for animal-related crimes, and most are funded independently, right? Do you also realize the staggeringly high correlation between violence towards / abuse of animals and violence towards people?
