Robbed in detriot

this past weekend my car was broken into when i went to see a concert at the Masonic temple in Detriot.  There were a lot of other people in the same lot who had this happen.  I'm sure most of us have been to musicals concerts and sporting events at night and as we drive by we see the expensive parking signs.  The closests lots are $20 while private fenced in parking lots go for much less.  So obviously i drive into that one.  Well perhaps we should all think twice about that becuase they didn't exactlly watch opver the lot they just took our money and left.  And another tip the police told me.  My mom left her purse under the floor mat so it wasn't even in plain sight.  They said someone probably watched her do it.  whenever you drive in a parking lot like that see if anyone is watching you.  Or just find somewhere where theres security.  Oh another thing the guy at the repair shop showed me how the guy did it.  He didn't smash it with a brick or anything he actually used a screwdriver.  clever for someone whos dumb enough to break into cars
