So what your saying is, that it is their own fault for being lied to and stolen from. Hmm..interesting out look on things that you have there.
So, if an 80 year old grandmother puts the chain lock on her door at night and forgets to bolt it, and on that same night a guy kicks in here door and kills her..it is her own fault for not making sure the deadbolt was active. Or you could say if a 20 year old girl is in a bar wearing a racy outfit, it is her own fault she was gang rapped later that night..I mean come on what was she thinking wearing clothes like that? She was practically begging for it.
Basically what you are saying is, if someone is the victim of a crime it is their own fault for not fully protecting themselves 100% of the time. It is their fault for trusting someone. So you must live in a vault, don't answer the phone and wear a tin-foil hat. That is the only way you can be 100% safe.
People make mistakes in life sure, but that doesn't make the crime any less a crime and it doesn't make a victim any less a victim. Justifying Mr Hinds actions by saying his victims should have investigated him better is basically saying that girl shouldn't have wore that dress to that bar. Your down playing the crime and the criminal.
