Yes. If the grounds for the arrest were lawful to begin with, the actual charge can be changed or amended at a later time.
"resisting arrest charge" no and we dont need you. DUI/DWI
It's all up to the prosecutor, judge, jury or possibly the arresting officer to change the charge from a felony charge to a misdemeanor charge, happens all the time..
He or she may apologize to the person and let them go.
It sounds from the question, as if the defendant was charged for TWO offenses. The one for which he was arrested, and the obstruction charge (when he apparently 'resisted' the arrest). . The question indicates that he was found not guilty of the original arrest charge, but WAS found guilty of obstructing the officer.
The officer can only make decisions on whether to arrest, cite, or not to arrest, referred to as officer discretion. The officer cannot (honestly) promise leniency of a charge because they do not have that authority. Charges are filed and issued by a prosecutor, not a police officer. Any statements given to a police officer based on a "promise of leniency" without the prosecutor's cooperation will be considered coerced and inadmissible.
If there was one officer battling to detain and put the person under arrest then that would be only one. If another officer had to come toassist...then there is a possibility that the second officer could also impose the second charge. Hence the person is now resisting the second officer. Usually they don't because it is more paperwork, court time for the second officer and the lead officer takes the collar. It basically depends on the circumstance of the severity of the resisting. If a second or third etc officer was spit on, hit or bit say; then additional resisting charges would appear valid per officer involved.
The person getting cited for being at fault for the accident gets belligerent enough to the point where it warrants their arrest, and they resist the officer arresting them.
A "sworn officer" is a police officer who has the full power to arrest someone for breaking the law, whereas an "unsworn officer" is oftentimes a volunteer who can assist the sworn officer, issue tickets and citations, but cannot make an arrest. In many jurisdiction, the sworn officer is also the only kind of of officer who can carry a gun at all times.
Depending on the jurisdiction you're in: "Obstruction of Justice" - "Interfering With A Law Enforcement Officer in the Performance of his duties - "Hindering An Officer... etc)" - "Assault On A Police Officer" - etc - etc. None of it is good.
The plural form is... 'officers in charge'.
Someone who can work but a judge may sentence them to weekends in jail from another charge. It is not the actual charge but a sentence.
In order to take you into custody they must charge you with an offense at the time of your booking. That being said... thee PROSECUTOR may change the arrest charge at any time up until you are presented to the court for your arraignment.
