Agree with what youve said, I find it unbelievable they only asked him to pull up his top, saw what they thought was a small bruise (how!!?? - it's obvious it was only the bottom of that large bruise photographed) and were content with that. To call concerned family members Malicious, also unbelievable.
Just one thing though, I don't believe Arthur was there to witness Gary's death. I've read lots on the case and can't see a child being present, I believe he was elsewhere at the time. If anyone can show me evidence he was there, fine, but I've certainly not seen that mentioned and it def would be.
