Tougher in criminal cases because of lack of resources and time to vet jurors.
In my jurisdiction, there is no voir dire, — with lawyers speaking with jurors. Hence, experience and instincts drive a lawyer’s judgment in jury selection.
Basic data is helpful, but so is body language. What kind of jurors I seek depends upon which “audience” is best suited to be sympathetic to client and the defense.
I was born with exquisite street smarts and ability to read people. So, I don’t need a fookin jury consultant.
