To make a summary arrest for a misdemeanor offense, GENERALLY, the officer must actually observe it take place (i.e.: it occurs within range of his senses). HOWEVER: Many(all?) jurisdictions list exceptions to this which involve more serious offenses, and which are known as "Probable Cause Misdemeanors," and an officer may make an arrest even though he may not have actually observed the crime. One jurisdiction's list (Washington DC) is typical: "Simple Assault - Petit Larceny - Unlawful Entry - Receiving Stolen Property - Attempted Burglary - Attempted Larceny - Attempted Auto Theft." The foregoing seven offenses are all codified as Misdemeanors, however they are the listed exception to the misdemeanor arrest rule, and an officer need not have observed them take place in order to make a summary arrest. CAUTION: Other jurisdictions exceptions MAY be different.
They can arrest them. of course,but what can they do to prove the suspect is guilty?...like fingerprint?
Misdemeanor Commit
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.
No. An arrest warrant is valid until it is served or cancelled by the court.
No. The arrest is not likely to be reported, but if you were fingerprinted, a copy of them will end up in the FBI database.
Not enough information is disclosed on what misdemeanor charge, or what "procedure" is being referred to. However: if it is a misdemeanor traffic offense, not generally. But if it is a summary arrest situation (i.e.: you are taken into full custody) for a misdemeanor offense, the exact same procedures and constitutional protections will apply as it does in any other arrest situation.

You have until there is time for a judge to hear the case.
