Do you know what is an arrest warrant exactly and why in certain cases the police will need it before they arrest someone? An arrest warrant is known as a judge’s order to law enforcement officers to charge someone with a crime, arrest them and bring them to jail for a crime they committed. Every individual with a warrant for their arrest can be arrested by the police at any time. However, arrest warrants cannot be issued indiscriminately, it will need such kind of a sworn statement from police officers, prosecutors, and also victims that the person has committed a crime. When the police attempt to arrest a person at home for a non-serious offense, they will need a warrant to arrest that person. But in lots of cases, a police will arrest somebody on an alleged crime right away and take that criminal to a municipal judge who will formally serve that individual with a warrant based on the officer's testimony. This happens when the police believe that a crime has been committed and the police are sure that the person committed the crime. An arrest warrant should include the name and address of the charged, specification of the crime, what law was broken, and most importantly a signature from a judge and the arresting officer. To get a warrant, the police must convince a judge that there is a cause to make an arrest, and when an arrest was made without a warrant, then the police have to convince a judge later that at the time the arrest was made there was probable cause to make an arrest. Warrantless arrests usually occur when there is a crime witness who gave a description of the perpetrator and the police see someone who fits the description. Typically, this is enough to justify the arrest of a person. Things like this do not apply to minor offenses, officers cannot make arrests without warrants to someone for minor crimes such as shoplifting without witness the crime themselves. Basically, police will need an arrest warrant if they're trying to arrest an individual in his or her home. However, the police could make an arrest without a warrant in a suspect's house if there are exigent circumstances such as when police chasing a suspect who had fled and hidden in his house, when police believe there is someone in the house who might be in danger, or if someone answered the door and allow the police to enter. In certain cases, the police may then justify an arrest without warrant, although it must be done in the suspect's house. And if a judge later rules that the  probable cause was  not enough for the police to arrest a person, an experienced lawyer is able to fully assess the situation and may argue that any evidence gathered through the course of an illegal arrest should be inadmissible during trial, but the consequences of an illegal arrest are evident in nature. If there is an arrest warrant issued for you, you need an excellent move to reduce or eliminate the consequences that you might face. Knowing that you have an arrest warrant can be a frustrating experience since it can lead to a criminal conviction. Just imagine  a police officer show up at your home unexpectedly or pull you over on a street. A warrant for arrest is issued by the Judge, so when the police show up, you can expect that police officers will honor that order. You need to take the time to seek the best results by discussing your situation with an experienced criminal lawyer.
