Don't say that to a CISF guy. They get really mad. I once interned at a national lab and there was a snafu due to which I couldn't get in. So I had to call my advisor from the main entrance, and I told him that the watchman isn't letting me in. The security guy overheard it and threw a fit about how he isn't a watchman but a central gov. employee.
Absolutely. In Indian hierarchy one can blast watchmen for not doing their work properly and CISF can blast a passenger for not doing their work properly. So they are indeed powerful. One can see that in their swagger. They are there to serve government not the passengers.
