Narco test is used only as a supportive evidence ,nothing more nothing less.Court do not punish someone on narco test analysis alone.
Except the t-shirt blood stains ( yet to get DNA nod)is the ONLY concrete evidence,but as stated earlier court do not punish guys with only ONE so called concrete evidence.All the three will get out on insufficient evidence.
