Reid is big on the "Pause and wait to make the interviewee blurt out more info"... they have some great videos you will watch, but understand, almost all the videos they show is private corporate investigations for theft, and the people being interviewed are there because their job told them to be.
Interviews of suspects and witnesses are not the same, nor are they the same as interviewing someone because their boss made them go to be interviewed. There are a few techniques taught which work pretty well, and there are several that are not going to work at all.
And just because someone looks up and to the left doesn't mean they are lying... (this used to be a biggie that Reid taught)
As stated above, the Feds used to be real big on the Reid technique and the "pause for the cause", but some of the techniques used caused confessions to be thrown out in court, so most of the Reid stuff is no longer taught at FLETC or used by any of the 1811 agencies who do criminal interrogations.
Take the class, enjoy the videos, and take all the different techniques with a grain of salt. There is some good info, but remember the foundation it was built upon. What works in corporate America may not work in a suppression hearing in a criminal court.
