The case of death sentence to rapist of a young girl in Punjab , and then the enhanced sentencing of a judge of Islamabad by high court for torturing a girl in house have one thing in common .
The principle of following and connecting chain of scientific evidence seems not to have been done . It is assumed in courts that a testimony of a medicolegal doctor on DNA evidence or torture is enough . This is not so in science .
For DNA evidence for example courts need to take evidence of
Man who took blood sample of suspect .
Man who sent the samples
Man who transported the sample
Man who recieved the sample
Man who put sample in analyzer machine
Person who read the results
Person who calibrated the machine
Machine capability and pitfalls managers
One independent person to analyze the whole .
Without above death sentence on Scientific evidence alone is not safe . If there is no witness .
Similarly in torture cases , the chain of person who saw first , the radiographer who took photos , the doctor who examined the child , and a neutral second opinion on the whole evidence is needed .
A psychological examination of accused is some times needed as well and best is done in henious crimes
