In Most States, a Citizen Can Only Make an Arrest

In most states, a citizen can only make an arrest for a crime committed in her or his presence, and the citizen's actions must be based on:

A) there being at least one witness present who inferred a crime occurred
B) reasonable suspicion that it occurred, even though in fact, no crime occurred
C) the fact that a crime must actually have occurred
D) probable cause that it occurred, even though in fact, no crime occurred
