selling insurance to someone with a clear disability was bad but for such a large company, one or two bad happening shall not be misused to say it was a common practice in Fig.  there are many policemen not behave to the standard - if rc make an inquiry surely there would have been more hairraising conducts - does that mean that the whole police force was so bad? I am upset to see that example being used again and again for propaganda purpose only.
