For assassins, two motives predominate: grievance and performance.
Grievance is a broad category, encompassing all manner of extremism, personal and political grudges, and anything else stoking anger.

PD&A - Three Common Errors Lawyers Make in Retaining Experts
Three Common Errors Lawyers Make in Retaining Experts
Park Dietz, MD, MPH, PhD
Since 1996, when PD&A began operation as a formal group, lawyers have inquired about many thousands of new cases, both civil and criminal. I’ve spoken directly to all of those who didn’t already know which experts they wanted to retain. While most of these lawyers were sophisticated about the use of experts, a surprising number seemed naïve about how to evaluate the fit between expert and case, how to judge hourly rates, and when they should retain. I share here some of the common errors lawyers make in seeking experts.
