DOVER, Del. (AP) — An expert in police tactics and use of force says he thinks a white police officer in Delaware delivered a "vicious blow" in kicking a black suspect in the head, breaking his jaw and knocking him out.
But a judge on Wednesday prohibited former San Jose, California, police officer Ron Martinelli from using the word "vicious" in testifying in the assault trial of Dover police officer Thomas Webster IV.
The judge also prohibited Martinelli from giving his opinion on the amount of force delivered to Lateef Dickerson's head, saying his estimate was too imprecise for scientific certainty.
