A good defense means a world of difference in court. Imagine going to trial without any concept of what could happen, no plan to defend yourself and no coaching on what to do when you're spoken to. It would be easy to make mistakes that could result in the loss of your case.
One of the things that people can often rely on in criminal defense is a good alibi. A good alibi can go the distance toward helping you avoid penalties. However, not all alibis are made equal.
What's interesting as time moves on is that more people are being arrested based on DNA evidence from cold cases. The invention of genealogy websites has made it possible to link more people to cases through their DNA, essentially solving many cases that no one thought would be resolved.
It can be hard to defend yourself when you have no alibi for a crime, but it's certainly not impossible. There are multiple ways to prove that you were not at the scene of a crime and that you've been falsely accused.
When you go to trial for a crime, there are some things you can do to make your life easier. From presenting yourself appropriately to offering respect to the judge, much of what you do will have an effect on your case.
