My signature has been brought up and tested more times than I can count in matters of chain of custody, case reporting and CSV in many of court rooms in many countries. Mine comes up with an average of 11%. Vomit eating lawyers who defend the scum we would pick up would try anything to throw a case or find a loop hole.
I got called once back in 2006 for a case against an American whose hobbies included cutting people up all over Europe. He was being presented in Croatia for extradition, he lawyered up as soon as we grabbed him. his lawyer attempted to test the judge by claiming that the arresting agent, the senior CSV, the official requester and the agent who fired his weapon could not be the same agent as all the signatures where not even close to being the same person, therefore the evidence collected is not verified as being real or even his clients property.
Delayed the extradition by 30 days, judge saw my signatures and said yes this needs to be explained. In the mean time the Lawyer had all the signatures tested by a so called expert wittiness who said that there was less than a 10% chance that all signatures belonged to the same person. But I ended up showing up for the hearing and ssaid right out that I purposely never use the same signature and proved on many other cases and legal documents I brought along with me. Judge saw how many others tried this crap before and let it all go.
Then suddenly since his extradition was granted and me and my Team where already there the perp claimed he could not be transported by me and my people because I shot him and he felt threatened. I told the judge that if I wanted him dead he would be, and used justifiable force. Judge said he did not care about that and asked the guy to stand up and point at the man who shot you, he pointed at me, the judge then asked the man he he saw the person who arrested him and he pointed me out again, then the judge asked him he if saw the man who delivered him to the hospital for medical care and releasing him over to local authorities and again he pointed me out.
Judge said so why was there any question ever as to who signed everything.
I know many of people who sign just like I do, I was raised to do it this way and I am sure it has been going on for a very long time.
