When you ask a person what it's like being arrested, a person can have a range of emotions. Complete shock can cause a person to have lack of memory as to the details of the arrest. Maybe they suspected it was coming, but didn't know what they would be charged with? Perhaps the accused just needs an opportunity to represent their side of the story.
If you or a loved one has been accused of a crime, every person has the right to defend themselves in a court of law. The prosecution may try to persuade the accused to offer a confession or a plea deal, but this often comes with not just being charged with a crime but convicted of one. It could be for a lesser crime than initially charged, so it's good to weigh your options.
There are many ways in which the process of being charged with a crime can go for the accused. It's possible that one has a definite response after being charged in which the charges can be dropped. Otherwise, building a criminal defense can be built on denial of a charge or explanation of actions relating to a charge. There could also be a legal technicality that could have a charge dismissed, and one should explore that option immediately if they believe that's the case.
Obviously, emotional reactions can come to the surface immediately when in the process of being charged with a crime. Understanding the charge and how to proceed is key to achieving the optimal outcome for the accused.
