<p>Any armed person who would admit to the cops that he was following someone, would have to be depraved if he thought admitting it would help him get away with murder.</p>
<p>In other words, one could argue that a person who takes the initiative to inform the police of his actions at several steps along the way and asks for their assistance in apprehending a suspicious person, does not fit the profile of a person intending to commit murder. It looks a lot more like good intentions gone awry.</p>
