Getting arrested can be a very stressful situation for pretty much anyone involved. The crime also plays a pretty huge role in the sort of situation you are going to find yourself in. Finding yourself getting arrested for something as incredibly serious as murder is definitely going to have an impact in your life, since this crime is arguably the very first thing that you could possibly have been accused of. It can be easy to give in to despair in situations such as this, because things do start to seem rather hopeless.
However, there are a few things that should be kept in mind if you do end up getting arrested for murder, things that are certainly going to give you a lot more hope about the future and help you become just a little bit more optimistic about how things are going to end up turning out for you in the long run. The first, and perhaps most important, thing that you should keep in mind if you find yourself getting arrested for something as serious as murder is that you are not guilty, at least not yet. You are only arrested because you are under great suspicion of murder, and while the situation is serious and even dire in a few circumstances in the eyes of the law you are still an innocent individual. The onus is on the justice system to find you guilty, until they are able to do so no one can call you a guilty man and you do not need to treat yourself as such either.
This is important because of the fact that people often forget the rights that they have when they are getting arrested, mostly because of the fact that they are panicking and feel scared that things might end up going sideways for them if they are not extremely careful. Another thing you should keep in mind, and this is related to the first point that was being made here, is that just because you have been arrested for something does not even mean that you are being charged with this crime, at least not yet. The important thing to remember is that getting arrested means you are a suspect, getting charged is a different story entirely. You cannot be forcibly detained at a police station unless you are being charged with something, so in this situation simply answer the questions you are being asked and then ask them if they are charging you, you are free to leave if this is not the case.
You also need to remember that you have rights while you are being arrested as well. You cannot be physically harmed no matter how serious the crime you are being accused of is, and you absolutely must be read your Miranda rights otherwise the entire case against you is going to be rendered moot.
