bhai mere cant say aything regarding politicians but regarding army officers, do u even know k what is punishment in army if u get caught having a non custom paid car?
it is straight away "court martial" of that officer of jawan with zero benefits of retirement etc.
there are proper fs sections (intelligence units who look out for officer's involved in illegal activities as such) and then u can also report such things if in sight to nearest army headquarters with proper application. and if u dont even want to do that u can go and report in excise department they can take further action .
just to assure u itni lut ni machi fauj me jitna log sochte hein
(u may check it from someone in army or who know well about army)
. plz don't just say out things
