Why won't Jeremy Kyle allow a lie detector test to be carried out if drugs or violence are involved in a relationship? The result of the lie detector isn't going to make the "offender" change their ways, so what's the reasoning behind JK's stance?
Most likely incase it ever goes to court and gets thrown out because people on the jury might have seen the programme, plus no one can defend someone properly if they failed a lie detector test on tv, they still entitled to be represented, even if they might be guilty.
