Cabbies on edge after third robbery

There are nervous cab drivers in the city. For the third time in two weeks a Roach's Taxi driver has become the victim of an armed robbery. In all three cases the taxi was stolen, but the driver wasn't hurt. Roach's owner Dennis LeBeau thinks the robberies may be isolated and hopes police can get those responsible off the street.  He says the drivers have come up with ideas they hope can be implimented to help prevent future occurances.
