I could go indefinitely. You just have to be careful in not getting caught, which is doable. Find an unregistered weapon w/ silencer. Purchase plenty of ammo. Practice your aim every day. Purchase body armor and carefully plan out your killings.
I think I would really enjoy that sort of revenge.
So what about all the trace and DNA evidence you leave?
DNA evidence barely stands up in court, especially if it's not collected in the victim's home. It is impossible to prove that you didn't happen to walk through that alley at some other time that day.
You've absolutely no idea what you are talking about. In fact, just go ahead and shutup and walk away.
Aactually Mill, he's right...all DNA would tell the cops is that he was at the crime scene sometime in recent history...could've been yesterday...could've been a month ago. If it is a public place that evidence is not very condemning. A private residence where the victim and suspect did not know one another? That is a little more condemning.
No, actually, he's not right and neither are you. Take a forensics class and get back to me. Your DNA is not going to randomly appear in a public place. The DNA they are looking for would be on the victim, or be a part of trace evidence that was left at a CRIME SCENE. Seriously, take a forensics class and you will understand DNA. Not only that, but DNA is not used alone. Other trace evidence such as fiber, hair, ballistics, etc are used. DNA is just used as statistically damning evidence in addition to other physical and trace evidence.
If you start going out on mass murder spree, you are going to be leaving trace evidence and/or DNA out there. There's no "well anyone could have done that." They use statistics. They can give probability in the billions and higher with nuclear DNA. With mitochondrial DNA it is less, but is still high enough to be very damning. If you link trace and DNA evidence over several crime scenes -- even macro scenes -- you have a very strong case.
So when you've got ammunition casings (if you left them), or the actual slug (check for striations and use ballistics to link the scenes), DNA and trace evidence -- then you've got an extremely strong case.
You bring up the ballastics expert. Sir, what are the chances that these slugs would match being fired from the same gun over x number of scenes? Oh, so many in a million or billion.
Next up is the DNA expert. Sir, what's the probability of another person on earth (minus an identical twin) having the same DNA as our suspect? Oh, one in 500 billion. It depends on what DNA database they use and the ethnicity of the accused, but DNA is a very proven science, and can produce very damning statistics.
Then you bring in the fiber expert. Sir, what did the fibers you recover tell you? Well, we were able to exclude the fibers from having occurred from the victims or any witnesses, and we matched 5 class characteristics of the fiber from the suspect to fiber found at the scene.
You people watch too much CSI. It is extremely difficult to get away with multiple crimes -- especially those that share an MO (and you will leave one), and ones that are linked by a multitude of trace, physical, and DNA evidence.
You claim the age of a sample can't be determined? Wrong. Let's say the sample was blood that the suspect left. Presumptive test of tetramethylbenzidine is positive. So what you ask, right? The strength of the reaction can give a rough age. So what? You know it is blood, so what? Ring-precipitin test provides confirmatory proof it is human blood. Then you start doing blood-typing. Rhesus, ABO Markers, Lewis System. Now you've narrowed the blood make-up of the person down to then provide even more statistical evidence that the person committed the crime.
People think that it is "real easy" to commit the perfect crime. It isn't. Most people get by due to incompetence of the investigating agency, weather, dumb-luck, or bungling of evidence.
You *WILL* leave evidence at the scene of a crime, and a gifted criminalist will bust your ass. Totality of evidence is the key -- DNA is just another part of the total, but is extremely hard to overcome. Unless you are going to explain how you were 1/500 billion, had fiber/hair at the scene -- or it was linked back to or discovered on you, ballastic evidence, etc. That's beyond a reasonable doubt and easily.
