Limited Exam to recruit more IPS Officers

This is with reference to the news in The Times of India . Government is p[lanning to appoint IPS Officers from governmeny servants already serving in armed forces and paramilitary forces. I think instead of conducting an exam for this purpose officers from these departments could be appointed on deputation (if required on higher posts), and young and fresh candidates should be appointed through civil services. Direct recruitment in All India Services was reduced in past due to which such kind of crisis is faced. It will be better to think rationally on this issue to avoid future crisis of this type in any of the government departments.
