When Delhi Police’s much-feted “encounter specialist” ACP Rajbir Singh was shot dead by a property dealer friend in the latter’s Gurgaon office back in 2008, there were immediate signs that something was not quite kosher. The then top cop ordered that nobody from the force was to attend his funeral. For a fabled officer credited with 42 “kills” and conferred with two out-of-turn promotions, a PRO was the sole representative of the 85,000-strong Delhi Police in attendance. The most nominal of gestures possible.
