Are there any entry barriers for fraudsters?

One point which i like about this article is that it reaffirms the belief that frauds normally happen to circumvent polices & procedures. So if you make some process very complex or offer some concessions on fulfillment of certain criteria, be prepared for frauds. They have given example of rise in fake high school certificates due to government law of of allowing 3 years visa to high school graduates. I feel same applies in corporate world too wherein if companies make complex structures for achievement of certain goals then people may find out a way to beat those complex structures. Old saying keep it simple stupid sounds so logical!

Reporting fraud-Serious Frauds Investigation Office

This office was setup with good intentions but haven't read much about work done by this office. I am sure they are doing lot of work but may be they don't share their success stories with public unlike similar organizations in western countries. Try visiting http://www.sfo.gov.uk/ and you will get an idea about what i am saying. I look forward to seeing Indian SFIO reaching this stage.
