From the police statement, there does not seem to be anything inappropriate, it did not even mention he was handcuffed. They were in plainclothes and not Police cars. So quite discreet arrangement appeared to be made indeed. However it is always good to review procedures for improvement like having an adult around for minor.
What's your point on saying the boy jumped becos "you say I am guilty, I am guilty then"? It is sad for his family that he jumped whether he is guilty or not. But let's not forget that there are also rape and molest victims who jumped or worse, are murdered.
I have pasted below this from the other thread on the policeman raped 16 year old girl case and this is the victim's feelings as recorded.
" According to a victim impact statement tendered to the court, the victim felt humiliated and ashamed by the episode and started to shun social gatherings and male counterparts. She also had thoughts of committing suicide.
The court also heard that the girl’s mother had to accompany her to sleep as she was fearful of being alone at night."
