Pockets of violence might develop, but we're a long way from widespread "lashing back." People are too comfortable. They have too much to lose. For example, striking a cop is (I believe) a felony. Faced with the option of spending years behind bars (and coming out with a felony) and walking away after getting hit with pepper spray, most would choose the latter.
It is a felony, but depending on how you do assault them it can be dropped to a gross misdemeanor or the equivalent where you are. That also depends on your past record and your lawyer.
