Actually representing large corporations and their executives who get into trouble, and then overseeing and working with top criminal defense lawyers in one's firm and some of the top defense lawyers in the country, gives huge insight into criminal laws, defense and matters. And any lawyer knows more about criminal laws and defense, than virtually all non-lawyers.
As an example, I worked closely with Ted Wells on an important matter. "Some of Wells' more notable clients include Michael Espy, Senator Robert Torricelli,[2], Scoter Libby and Congressman Floyd Flake.[10] He represented former New York Governor Eliot Spitzer against allegations stemming from his alleged involvement in a prostitution ring.[11] In November 2013, the National Football League hired Wells to prepare a report on a bullying incident with the Miami Dolphins involving Richie Incognito.[13] The report, released on February 14, 2014, made headlines for its finding of "a pattern of harassment".[14 He also represented the NFL in Deflategate. https://en.wikipedia.org/wiki/Ted_Wells. I hired Wells and worked closely with him. I later gave him permission, on behalf of my client, to represent Mike Espy. He won that case in a jury trial. I've been hired as an expert in several criminal matters/trials.
Knowing facts of a matter is also very important to understanding a case.
