As a general rule misdemeanor crimes must be witnessed by, or occur "in the presence" of the arresting officer. However many(all?) states have exceptions to this general rule that allow the police to arrest for probable cause for certain stated misdemeanor crimes the same as felonies. [As an example; the District of Columbia allows the local police to arrest for eight misdemeanor offenses (known as "probable cause misdemeanors) - they are: Simple Assault - Petit Larceny - Unlawful Entry - Receiving Stolen Property - Attempt Larceny - Attempt Burglary and - Attempt Stolen Auto.] I would imagine that other jurisdictions may have slightly different eligible misdemeanors, but they are probably similar in nature to the above examples.
The question is not sufficiently specific. Where and over what period?
Warrants can be used for both felonies and misdemeanors.
Probable Cause is more than mere suspicion but less than the amount of evidence required for conviction. Articulable Probable Cause must always be present and is the essential minimal justification for arrest.
Each agency has its own threshhold level for the allowance of minor misdemeanors by their applicants. Generally speaking however, any assault arrests would probably disqualify you from consideration.
The 4th amendment says that a search warrant must be needed for a place to be searched, and the persons or things to be seized probable cause applies to all arrests
If you've been taken into custody and are no longer free to walk away, you've been arrested. The U.S. Constitution authorizes arrests only if the police have "probable cause" to believe that a crime was committed and that the suspect is responsible. Probable cause is a loose standard and even if a person ends up being innocent, if the police had probable case then the arrest is constitutional.
No, it is pretty well established in case law that that arrests for minor violations such as those of municipal regulations, traffic or DMV offenses, and some minor misdemeanors do not necessarily require the defendant to be Mirandized.
"Probable Cause" is the foundatiion on which all arrests are based. It is a reasonable belief that a person has committed a crime. The test for whether probable cause exists for the purpose of an arrest is whether facts and circumstances within the officer's knowledge are sufficient to warrant a prudent person to believe a suspect has committed, is committing, or is about to commit a crime.

Because most offenses occur within their presence or under conditions under which there is 'fresh pursuit. Also, due to the fact that the identify of the actual offender and their physical appearance, and addresses of the wanted offenders is known. Warrants are necessary for offenses in which the identity of the offender is not immediately known or clear, and require investigation and the development of probable cause to make an arrest, or for misdemeanors which do not occur in the officers presence. Traffic offenses are, of course, self-explanatory.
(in the US) The law requires only one reason - Probable Cause to Believe that the person arrested is the one who committed the offense. This applies to ALL crimes.
The officials arrests Manjiro and his friends.
The Fourteenth. Which reads: The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
