DeSelby, a suspect a good number of thugs are caught by people who report "suspicious activity" to the police (and subsequently actually follow the given advice) when the police are actually able to conduct am investigation and find out what's going on. Maybe some "suspicious people" turn out to be honest people who were lost, or whatever.
The kid undoubtedly had every right to be there.
How do you know? Did
YOU investigate the crime? Is anyone so sure of the facts they can pass edicts like this? The deceased apparantly did have some record, although --apparantly -- he'd done nothing to justify the shooting at the particular point this tragedy went down.
Had he not been shot, it's impossible to say what would have happened.
All of which sorta makes me think calling the police might have been the last smart thing that vigilante did.
