Dear do you even know what you are talking about? NAB is the superior most civil organization with best salaries. The cases are made by the officers you are talking about. CSPs are summoned at nab offices and they have to appear before a 17 grade officer whether he be a secretary or anyone for that matter. NAB officers enjoy more protocol than that of CSPs. Infact at times, ACs, ADCs etc are appointed as focal persons or protocol officers for ADs when they go for field visits. N when on field visits you can take a police constable or two. Even if that is not enough, u can call the concerned dpo n ask for as much force as u want. However, when u join such organizations you are least thirsty for protocol or power, knowing u have them already. Your comment clearly depicts you do not have any idea about the organization. Even if you are part of it, you have not used your power for once. Besides, csps, politicians n say any civil post, nab is above them all, in terms of power they enjoy. U get selected at nab, not for once you would have to attend any office even for your personal chhote or baray kam. A phone call would suffice even if it is to a CSP of higher grade. No other office even matters to you when you are at NAB. Talking about power, atleast for once turn on the tv n that is what everyone is yelling on how nab has been given sweeping powers. Talking about other departments, they have more political intervention n influence of multiple offices. Nab does have internal pressure and that too only if you are lazy n not working upto the mark. Trust me.
