Ever heard of anyone actually using citizen's arrest in the US? I haven't. I bet the person making the citizen's arrest would get in more trouble than the person doing the crime -- kidnapping, lawsuit for potentially harming the person, etc.
I'll take the bet. The fact that you never heard of anyone using (making a) citizen's arrest is more of a commentary on the limits of your knowledge than the frequency of such arrests in US jurisdictions. Security personnel in all kinds of business establishments routinely make citizen's arrests of shoplifters, vagrants, con men, drunk and disorderly persons, etc. In a prior life I used to train such security personnel on how to make such arrests. They restrain the offender, explain why, and then call the police to continue the criminal process. Reasonable physical force is allowed to restrain the offender.
Far from constituting a dictatorial act (hard to comprehend that silly accusation) I think the right to arrest lawbreakers benefits society. If a person is breaking the law (even a misdemeanor) what is so bad about allowing private citizens to detain and bring the perpetrator to authorities? Would it be wrong to apprehend a purse snatcher if one had the ability to do so? A pick pocket? A drunk and disorderly person harrassing some senior citizen less able to defend herself? A professional dog walker who refuses to clean up after several of his wards make a poop? A private citizen who allows his dog to leave a steaming pile of crap in the middle of a well traveled sidewalk? Unreasonable arrests will be deterred by exposure to false arrest, false imprisonment, defamation etc claims by the wrongfully detained person.
In reply to Davidglen's comment distinguishing between misdemeanors and felonies, while what he says may be the law in Buenos Aires, the law in most US jurisdictions is that a citizen's arrest is authorized for any misdemeanor committed in the presence of the citizen effecting the arrest. The arrest for felonies doesn't even require that the criminal act be committed within the presence/observation of the arrestor, but I can not now recall the exact parameters for effecting an arrest in the case of a felony. Moreover, if I recall correctly, the law of civil liability provides protection for claims such as false arrest, fales imprisonment, defamation, etc based upon an erroneous, but reasonably executed citizen's arrest.
If private citizens could arrest irresponsible and anti-social dog owners for not picking up after their animal, there would be a lot less dog shit on BA sidewalks. Even the possibility of such an arrest would be a deterrence to violations.
