NO. Escape can only occur after a lawful arrest has been made. An example would be at any point from the time the offender has been taken into custody through the service of any period of judicially imposed incarceration. Resisting Arrest is a separate criminal act and it occurs when a law enforcement officer is attempting to affect an arrest. It could be any act (even passive) from refusing to comply to running away from the officer. Most municipal and county governments throughout the U.S. have and additional ordinance know as "failure to stop on lawful command" This ordinance can further assist the officer in gaining control over a suspected offender/suspect.
Arrest
(in the US) In many locations arrest/detention on grounds of "suspcion" is still a lawful statute - yes - they can.
Physical efforts to oppose a lawful arrest; the resistance is classified as assault and battery upon the person of the police officer attempting to make the arrest.
Search of a vehicle in conjunction with a lawful arrest.
That appearance is known as the arraignment.
An arrest refers to the lawful deprivation of the freedom of an individual by a peace officer. A police officer may arrest a person if he reasonably believes a crime has been committed without a warrant.
Fleeing an open warrant "flight to avoid prosecution" is similar to arrest resistance but "resisting arrest" occurs as you use force to avoid being placed under custody.Added: You NEVER have a lawful/legal "right" to "resist" police in the performance of their duty. You must submit, and if it subsequently turns out they had no lawful right to arrest you then you can bring court action against them for damages.
Yes. If the grounds for the arrest were lawful to begin with, the actual charge can be changed or amended at a later time.
A police officer can make an arrest in any location that he has a lawful right to be. You should contact a local attorney with information on your specific problem.
U.S. v. Robinson
Arrest powers are by the individual states, and generally include the power to arrest and deliver based on lawful information or probable cause.
(Answer is applicable to the USA only): A warrantless arrest is never served. A warrantless arrest is performed. Following the warrantless arrest, the arresting individual (typically) or authority is required (usually) to provide the courts with a warrantless arrest affidavit wherein the person making the arrest articulates the probable cause for the arrest, which then is submitted to a judge for review. The arrested person will already be in jail or otherwise in custody (and possibly even bonded out), before the signed warrantless arrest affidavit becomes available to the arrested person.
