Robbed at gun point

Good morning <br> <br> About a month ago I was robbed at gun point in the parking area and made a complaint and I was told that they would get back to me and have yet to do so.<br> On the day after it happened securities could tell me that those guys are usual suspect's at the mall. What I want to know is what is being done to stop this from happening to anyone else,robbed Samsung S3 which was 5 months old and no insurance. After sitting in the security office watching surveillance footage to see if we could get a picture for the police,I heard a lot of things that was happening there,there also so an incident whereby a security's radio was taken off. Cleaning staff and security said there was little they could do as these guys have guns and when they do something to protect customers these gang members wait for them after work. So my question is why don't they make this aware to the public or is losing business more important,because if I was aware of this I would have never waited in the parking lot on my friend. Now instead I am sitting without my phone and scared emotionally
