Well lets ignore the lies and myths and just concentrate on the Biblical evidence that you alleged, otherwise it's gets too messy.
"Pilate, a man who knew his crucifixions if anyone did, was surprised to hear he was dead. It normally takes days to die on the cross."
So are you saying that everyone who was crucified took two days to die? If so, please site your evidence for this claim.
"The other two were still alive."
Were the other two, scourged and beaten to the same degree before they were crucified?
"When he was stabbed with the spear, blood and water gushed out, dead bodies don't bleed "
NO they don't, but when the heart stops pumping, blood pools and will 'bleed' if a wound is inflicted in that area.
"(I'm aware of one explanation for that, but the spear would have to have been so precisely placed that I think it is most unlikely)"
So we have 'what you think' vs eyewitness testimony from someone who was there along with a modern medical explanation for the event? Hmm, what a hard choice. :)
"Somebody unrolled the embalming cloths in the tomb -"
