I cannot force SFST, not sure where that is coming from. That issue has never come up in court for me. They either performed them or they didn't. I cannot force someone to comply.Where is this legal obligation to take FST's coming from? If they are presented to a subject as involuntary, they are not going to be admissible in court most likely.
Also, the only way that a PBT is admissible in court is solely for a showing of PC.
