These DU folk and other Libs and Progs like them won't allow themselves to understand the concept of "deadly force". Guns and knives are but two examples. Trying to run some one down or crash into their car is deadly force. Whatever her reason for doing so, this female assaulted a police officer (more than one?) using deadly force. Shooting her was justified. Slamming some one's head into a hard object, such as concrete, is deadly force. Prog-St. Trayvon did that to George Zimmerman, so shooting him was valid self-defense.
And, seriously, how hard is it not to try to run down a police officer, crash into a police car, or slam some one's head into the concrete sidewalk? I've avoided doing such stupidity for over 6 decades, and won't claim to be a genius.
