hollywood703:There has to be a crime commited to have an arrest...regardless of LEO or citizen....Example....using original example...If OP is caught by property owner for trespassing....and wants him arrested (citation) for it, the OP cant turn around and say I want the property owner arrested......there is no crime committed (unless there is some other circumstances...such as an assault etc.)
No there doesn't have to a crime committed, there has to be an *allegation* of a crime committed. Maybe they are the same thing in a perfect world, but we do not live in a perfect world. News flash - sometimes people lie (officer, he smacked me). And sometimes - gasp - people are even found Not Guilty.
