[SCOFFS] UM... LADIES AND GENTLEMEN, ON BEHALF OF THE FACULTIES OF CRIMINOLOGY OF GHENT AND ANTWERP, I WOULD LIKE TO WELCOME YOU ALL HERE TODAY...

SO WELCOME.

HEH!

[SCATTERED CHUCKLING] AHEM.

AS SOME OF YOU MAY ALREADY KNOW, OUR ESTEEMED COLLEAGUE, PROFESSOR VERHERSTRAETEN, HAS SUDDENLY PASSED AWAY.

I WOULD LIKE TO INVITE YOU IN A MINUTE OF SILENCE TO HONOR HIS MEMORY.

♪ THANK YOU.

AND NOW I WOULD LIKE TO PRESENT TO YOU OUR KEYNOTE SPEAKER, PROFESSOR ROBBERECHT.

HE WILL TALK ABOUT THE HISTORICAL AND CULTURAL BASIS OF STATISTICS IN CRIMINOLOGY.

LADIES AND GENTLEMEN, PROFESSOR ROBBERECHT.

[APPLAUSE] ♪ ROBBERECHT: AND THEREFORE, I CANNOT STRESS ENOUGH THE IMPORTANCE OF STATISTICS.

THEY HELP US TO MAKE THE CORRECT ANALYSIS OF CRIMINAL BEHAVIOR AND MAKE IT POSSIBLE TO LOOK FOR THE APPROPRIATE SOLUTIONS.

♪ AND CONSEQUENCE OF THE HUMAN BEHAVIOR AND ARE OF THE UTMOST IMPORTANCE... [ROBBERECHT CONTINUING INDISTINCTLY] ♪ AH!

♪ ROBBERECHT: I THANK YOU FOR YOUR ATTENTION.

[DELAYED APPLAUSE] LADIES AND GENTLEMEN, MAY I ASK YOUR ATTENTION AGAIN FOR OUR SECOND SPEAKER, PROFESSOR JASPER TEERLINCK?

[APPLAUSE] TODAY, I WOULD LIKE TO TALK ABOUT INVESTIGATIVE INTERVIEWING, AND MORE PRECISELY, ABOUT DETECTING DECEPTION.

NOW, I GUESS SOME OF YOU PRETENDED THE LECTURE OF MY COLLEAGUE TO BE INTERESTING, SO YOU ALL KNOW ABOUT DECEPTION, DON'T YOU?

[AUDIENCE CHUCKLES] OF COURSE, WITHIN CRIMINAL JUSTICE, THE DETECTION OF DECEPTION HAS OBVIOUS RELEVANCE, AND CAN LEAD TO UNHOPED CONFESSIONS.

♪ TEERLINCK: IN A TRADITIONAL INVESTIGATIVE INTERVIEW, THE INQUIRER TRIES TO GATHER INFORMATION WHICH THE DEFENDANT REFUSES TO GIVE... ♪ UNLESS HE OR SHE WANTS TO LEAD THE INQUIRER TO A CERTAIN DIRECTION.

NOW WE CALL THIS THE INTERROGATION GUIDED BY THE DEFENDANT.

♪ TEERLINCK: NOW, AGAIN, I WOULD LIKE TO STRESS OUT THAT THE EXAMPLE I USE IS PURELY FICTITIOUS.

♪ ♪ TINE: ALEX?

♪ ♪ TEERLINCK: VOLUNTARILY FALSE CONFESSIONS ARE HARD TO DISCOVER.

CERTAINLY, IF THE CONFESSOR ACTS OUT OF THE GOODNESS OF HIS HEART, THERE IS NO EVIL.

♪ THERE IS NO EVIL IN HIS LYING, SO THERE IS NO DESPAIR IN HIS OR IN HER EYES.

♪ THANK YOU.
