xpmachina,

I suspect that the DA will be displeased with your refusal to submit to a polygraph interrogation. I doubt, however, that a judge will force you to submit. In the United States, it is impermissible for a judge to order a suspect in a criminal case t submit to a polygraph interrogation. However, in your country, the law may be different, so it would be best to check with a lawyer.

If pictures and/or key details of the crime scene were made public, this could indeed make use of the GKT format unfeasible. And if the police indeed tried to set you up, that would be additional strong reason for you not to submit to a polygraph "test," because polygraph "tests" can be rigged by the polygrapher to produce the desired result.

Again, I strongly suggest that you seek the advice of a criminal defense attorney.
