By Jon Katz

    Criminal defense is battle, and sometimes war. Following is a list of expert witnesses -- and sources for finding them, as well as other relevant information sources -- that I will occasionally update. Some I have worked with, and others I have heard about through recommendations or otherwise. Consequently, quality will vary. I welcome recommendations for additions to this list. 

Caveat emptor: Credibility is key with every lay and expert witness, both in terms of (1) the expert's honesty (the expert's credibility can be enhanced if the expert has worked in law enforcement, has testified for the prosecution or can explain why the expert has not so testified (e.g., with drug chemists, the prosecution has its in-house witnesses), background, likelihood to qualify as an expert witness, and ability to perform in court (not only on the witness stand, but also for cooperating with the lawyer's, client's and court's schedules) and (2) the lawyer's ability to help the expert be understandable, credible, and likeable to the jury. A good basic article is here for using and finding experts for criminal cases.
